CROSS REFERENCE TO RELATED APPLICATION

[0001] This application is a continuation-in-part of U.S. nonprovisional application Ser. No. 19 / 051,594 filed Feb. 12, 2025, which in turn claims the priority benefit of U.S. provisional application No. 63 / 563,395 filed Mar. 10, 2024. Each of the aforementioned applications is incorporated herein by reference in its entirety.INCORPORATION BY REFERENCE

[0002] This application is related to U.S. provisional application No. 63 / 538,265 filed Sep. 13, 2023, and U.S. nonprovisional application Ser. No. 18 / 830,125 filed Sep. 10, 2024, and Ser. No. 19 / 051,594 filed Feb. 12, 2025. Each of the aforementioned applications is incorporated herein by reference in its entirety.BACKGROUND

[0003] The present invention relates to weapon accessories and, in particular, to a weapon accessory riser assembly for a weapon accessory device, wherein the riser assembly has an integral camera.

[0004] Weapon accessories, such as sighting systems, are often mounted on an upper receiver or handguard of a weapon. Typically, they are positioned to align with a shooter's natural eye level assuming a standard cheek weld on the weapon stock. However, in certain operational environments, users may be required to wear personal protective equipment (PPE), such as gas masks or respirators. When wearing such equipment, the presence of such PPE my prevent the user from bringing their eye into alignment with standard height sighting systems, thereby forcing the shooter into an awkward or unstable shooting position or, in some cases, preventing use of the sighting system altogether.

[0005] In addition to interference caused by facial protective equipment, certain modern weapon handling techniques can obstruct the user's line of sight by positioning the hand in a manner that blocks the field of view through standard-height sighting systems. For example, as shown in FIG. 46, there is shown a weapon operator holding a rifle using a conventional “C grip,”“C-clamp grip,” or “thumb-over grip,” which can be utilized for certain shooting techniques and tactical scenarios, or, as a matter of individual preference. In this context, the shooter typically holds the rifle with one hand on the pistol grip, as usual, and the other, support hand is positioned toward the fore-end of the rifle with the thumb positioned over the top of the handguard. While this grip provides good control and stability of the rifle, particularly during rapid or sustained fire, positioning the support hand over the top of the handguard and at the fore-end of the rifle can potentially block scopes, sights, or other aiming devices mounted on the accessory interface, thereby obstructing the operator's sight picture through the aiming device.

[0006] These limitations underscore the need for elevated sight mounts to ensure unobstructed visibility while maintaining proper ergonomics.

[0007] A riser is an accessory that attaches to a weapon accessory mounting platform and raises the mounting point of the aiming accessory device. Elevating the aiming device above the handguard creates additional clearance to accommodate facial protective equipment as well as for the support hand, allowing the operator to utilize the C-grip without obstructing the line of sight through the aiming device or, in the case of a laser sight, without blocking beam emitted by the aiming laser.

[0008] The present invention contemplates an improved riser assembly with power supply which utilizes the space beneath the riser, which would normally be wasted or unused space, wherein the riser houses one or more batteries and a camera assembly while elevating an aiming accessory to accommodate a C grip or thumb-over shooting technique.SUMMARY

[0009] The present disclosure provides a riser assembly housed within a riser assembly and a weapon system employing the same, as described herein. In one aspect, aa riser mount system for a weapon, comprises a housing having a lower surface configured to engage a weapon accessory interface. An upper surface opposite the lower surface is configured to engage a fire control system. A peripheral wall extends between the lower surface and the upper surface and the housing defines an interior compartment. A riser circuit assembly is disposed with the interior compartment, which is configured to receive one or more batteries for electrical coupling to the riser circuit assembly. An electrical connector is disposed on the upper surface and structured and operable to electrically couple the one or more batteries to the fire control system. A camera assembly is disposed within the interior compartment. In the preferred embodiments, camera is oriented to record a field of view corresponding to a direction in which the weapon is aimed.BRIEF DESCRIPTION OF THE DRAWINGS

In embodiments, the connector assembly 92 is compatible with a modular attachment system featuring a series of elongated slots along the handguard or accessory mounting surface wherein accessories are attached affixed using locking T-shaped fasteners inserted into the slots and tightened to secure the accessory in place.

[0098] In the illustrated embodiment, the connector assembly 92 is a M-LOK™ connector configured to detachably couple to a selected one of a plurality of slots 94 in the weapon accessory interface. In embodiments, the slots 94 are compatible with an M-LOK™ (Magpul Industries Corp., Austin, TX) compatible mounting interface or similar system. It will be recognized that other types of weapon accessory interfaces are also contemplated.

[0099] The connector assembly 92 is coupled to an electrical cable 96 which has an electrical connector 98 disposed at the distal end thereof. In operation, the cable 96 is disposed interiorly of the handguard assembly B. The electrical connector 98 is disposed with a complementary notch 100 within the handguard assembly B and electrically engages with the connector 84.

[0100] Referring now to FIGS. 18-26 and with continued reference to FIGS. 1-7, 7A, 8-17, and 45, The keypad assembly H includes a housing comprising an upper housing shell 102 and a lower housing shell 104. A keypad circuit assembly 106 is received within an interior compartment 108 within the housing assembly 102, 104. The keypad circuit assembly 106 is operably and electrically coupled to the handguard circuit assembly 80.

[0101] In embodiments, the shells 102, 104 are secured via threaded fasteners (not shown) passing through clearance openings 111 in the shell 104 and threadably engaging aligned complementary openings in the shell 102.

[0102] A light emitting element 110 is disposed on the keypad circuit assembly 106. The light emitting element 110 may be a light emitting diode (LED), incandescent light source, halogen light source, laser emitter, and so forth. The light emitting element 110 is aligned with a port 112 on the upper shell 102. In certain embodiments, one or more lenses or other optical elements 115, such as one or more refractive or diffractive optical element are disposed within the aperture 112 to focus, spread, or otherwise shape the optical output of the light emitting element 110. In preferred embodiments, the optical output of the light emitting element 110 is in the infrared (IR) range although other wavelengths are contemplated. In preferred embodiments, the light emitting element 110 and associated optics are configured as a wide angle illuminator configured to emit light over a broad area, although embodiments with a more focused or narrower beam angle are also contemplated.

[0103] The keypad circuit assembly 106 is operably coupled to a plurality of button or key actuated switches 114a, 114b, 114c. The keypad assembly H and light emitting element 110 are powered by the riser assembly F. In operation the light emitting element 110 and switches 114a, 114b, 114c are configured to be electrically coupled to a selected one of the batteries 32, 36. The light emitting element 110 can be activated by the keypad buttons or by user interface elements disposed on the fire control system G which are coupled to the keypad assembly H via the riser assembly F. The forward mounting position of the light emitting element 110 on the housing shell 102 allows for minimum interference of the optical beam due to shadowing caused by the barrel of the weapon. The forward mounting position also minimizes reflections off the muzzle of the weapon back into the operator's field of view. In embodiments, the keypad assembly H can be moved to multiple positions along the handguard of the weapon to allow for user preference.

[0104] In embodiments, the switches 114a, 114b, 114c are provided with different switch covers having distinctive shapes or features to enable operation without the need for visual confirmation of the button being selected. In embodiments, the button 114a has a longitudinal ridge, the button 114b has a dome or smooth shape, and the button 114c has a transverse ridge. Other shapes or configurations are also contemplated. Allowing the operator to identify the desired button tactically enhances operational efficiency, minimizes the risk of errors, allows for button identification in low light conditions and in high stakes situations where the need to visualize the buttons could sacrifice situational awareness. In embodiments, a raised rib, ridge, or similar divider 117 is disposed between the buttons 114a, 114b and the button 114c is disposed on an angled or inclined portion of the housing to differentiate it from the other buttons, to allow the operator to activate the desired button without inadvertently pressing the wrong button or multiple buttons simultaneously. Providing such a divider 117 also allows an operator to differentiate button locations by feel.

[0105] Referring now to FIGS. 27-35 and 35A-35C, and with continued reference to FIGS. 1-7, 7A, 8-26 and 45, the flashlight assembly I includes a flashlight head portion 116 and a body portion 118. In embodiments, the flashlight head 116 includes a light source, such as one or more LEDs or other light emitting elements, such as incandescent, halogen, or laser light sources, a reflector, lens, and bezel, as would be understood by persons skilled in the art. The flashlight assembly I is configured to plug into a common point 100 on the handguard assembly B via the plug 98, and is powered by the power sources 32, 36 within the riser assembly F. In embodiments, the flashlight assembly I docs not contain a battery. This allows the flashlight assembly I to be as compact as possible. As best seen in FIG. 35A, the plug 98 is received with the receptacle 100. A threaded fastener 43 passes through a clearance opening 45 in the plug 98, and threadably engages an aligned opening 47 within the connector receptacle 100.

[0106] The flashlight body 118 is coupled to the connector assembly 92 attachable to the handguard interface assembly 90 via threaded fasteners 91. The connector assembly is advantageously an M-LOK compatible connector. In FIG. 17, the handguard interface assembly 90 is shown exterior of the handguard assembly B for case of illustration, although it will be recognized that in operation the connector assembly 92 is disposed within the handguard assembly B with electrical connector elements accessible though the slot 94 to which It is attached. The cable 96 is preferably relatively short and flexible, with sufficient length to allow the flashlight assembly I to be positioned at any point on the perimeter of the handguard assembly B. In this manner, the power routing to the flashlight assembly I is done completely inside the handguard assembly B with no exposed cables.

[0107] As best seen in FIGS. 35B and 35C, for case of illustration, there is shown a fragmentary portion of the handguard assembly B including a mounting slot 94. The connector assembly 92 is disposed within the interior of the handguard assembly B and includes an upstanding boss 49 which is received within and is complementary in shape with the slot 94. The threaded fasteners 91 pass through aligned clearance openings 51 in the flashlight body 118 and through the slot 94 and threadably engage openings 53 in the connector assembly 92. The fasteners 91 provide a clamping force between the flashlight assembly I and the connector assembly 92 to secure the flashlight assembly I to the handguard assembly B. The electrical connector 55 is disposed on the boss 49 and engages the complementary connector 57 on the flashlight body 118 for electrically coupling the flashlight assembly I to the riser assembly F via the handguard circuit assembly 80.

[0108] Referring now to FIGS. 36-44, and with continued referenced to FIGS. 1-7, 7A, 8-35, 35A-35C, and 45, there is shown an alternative embodiment keypad assembly H′ which is as described above by way of reference to FIGS. 18-26, except that the keypad assembly H′ additionally houses a camera assembly 120 (see FIG. 45) for imaging a scene within the field of view of the camera assembly 120. The camera assembly 120 includes a lens assembly to capture video footage and a sensor array (e.g., a charge-coupled device (CCD) array or a complementary metal-oxide-semiconductor (CMOS) array) for converting incoming light into electrical signals and a processing unit for storing digital representations of an imaged scene as would be understood by persons skilled in the art. The camera assembly may be configured to record and / or transmit still images, video images, or both. In situations where additional illumination is required to enhance visibility or highlight specific details within the imaged scene, the integrated light emitting element 110 can be activated. The light emitting element 110 and camera assembly 120 are powered by the batteries 32, 38.

[0109] The keypad assembly H′ includes a housing comprising an upper housing shell 102 and a lower housing shell 104. A keypad circuit assembly 106 is received within an interior compartment 108 within the housing assembly 102, 104. The keypad circuit assembly 106 is operably and electrically coupled to the handguard circuit assembly 80. In embodiments, the shells 102, 104 are secured via threaded fasteners (not shown) passing through clearance openings 111 in the shell 104 and threadably engaging aligned complementary openings in the shell 102.

[0110] A light emitting element 110 is disposed on the keypad circuit assembly 106. The light emitting element 110 may be a light emitting diode (LED), incandescent light source, halogen light source, laser emitter, and so forth. The light emitting element 110 is aligned with a port 112 on the upper shell 102. In certain embodiments, one or more lenses or other optical elements 115, such as one or more refractive, diffractive, or protective optical elements are disposed within the aperture to focus, spread, or otherwise shape the optical output of the light emitting element 110. In preferred embodiments, the optical output of the light emitting element 110 is in the infrared (IR) range although other wavelengths are contemplated. In preferred embodiments, the light emitting element 110 and associated optics are configured as a wide angle illuminator configured to emit light over a broad area, although embodiments with a more focused or narrower beam angle are also contemplated.

[0111] The camera assembly 120 is coupled to the keypad circuit assembly 106. The camera assembly 120 is advantageously a digital camera and may be a daytime camera, low light camera, infrared camera, thermal camera, etc., and may be a still image camera or video camera. The camera assembly 120 is aligned with a port 122 on the upper shell 102. In certain embodiments, one or more lenses or other optical elements 125, such as one or more refractive, diffractive, or protective optical elements are disposed within the aperture 122 to focus rays from a scene being imaged.

[0112] The keypad circuit assembly 106 is operably coupled to a plurality of button or key actuated switches 114a, 114b, 114c. The keypad assembly H′ light emitting element 110, and camera assembly 120 are powered by the riser assembly F. In operation the light emitting element 110 and switches 114a, 114b, 114c are configured to be electrically coupled to a selected one of the batteries 32, 36. The light emitting element 110 and camera assembly 120 can be activated by the keypad buttons or by user interface elements disposed on the fire control system G which are coupled to the keypad assembly H via the riser assembly F. The forward mounting position of the light emitting element 110 on the housing shell 102 allows for minimum interference of the optical beam due to shadowing caused by the barrel of the weapon. The forward mounting position also minimizes reflections off the muzzle of the weapon back into the operator's field of view. In embodiments, the keypad assembly H can be moved to multiple positions along the handguard of the weapon to allow for user preference.

[0113] In embodiments, the switches 114a, 114b, 114c are provided with different switch covers having distinctive shapes or features to enable operation without the need for visual confirmation of the button being selected. In embodiments, the button 114a has a longitudinal ridge, the button 114b has a dome or smooth shape, and the button 114c has a transverse ridge. Other shapes or configurations are also contemplated. Allowing the operator to identify the desired button tactically enhances operational efficiency, minimizes the risk of errors, allows for button identification in low light conditions and in high stakes situations where the need to visualize the buttons could sacrifice situational awareness. In embodiments, a ridge or similar divider 117 is disposed between the buttons 114a, 114b and the button 114c is disposed on an angled or inclined portion of the housing to differentiate it from the other buttons, to allow the operator to activate the desired button without inadvertently pressing the wrong button or multiple buttons simultaneously.

[0114] Now referring to FIGS. 47-53 and with continued reference to FIGS. 8-16, views of a weapon A′ appear in FIGS. 47-51. The weapon A′ is similar to the weapon A in many respects, but differs in its replacement of the riser assembly F with a riser assembly F′, which includes an integral camera assembly 126 (not to be confused with the camera assembly 120, which is optionally housed in the keypad assembly H′, as discussed above). The weapon A′ also includes an alternative embodiment handguard assembly B and accessory rail D. In the weapon A′, the upper portion of the handguard assembly includes a conventional Picatinny rail D.

[0115] With reference to the embodiment appearing in FIGS. 1-7, 7A, and 8-17, as shown most clearly in FIG. 17, the riser assembly F is attached to the riser mounting portion 52 of weapon A through the interlocking nature of recess 54 and aperture 56 with electrical connector 46 and protrusion 44, respectively. In certain embodiments, the riser assembly F′ appearing in FIGS. 47-53, F″ appearing in FIGS. 54 and 55, and F′″ appearing in FIGS. 56 and 57 may be adapted to be similarly attached to handguard / rail system of the weapon A appearing in FIGS. 1-7 and 7A.

[0116] However, in the embodiment as shown in FIGS. 47-53, and as shown most clearly in FIG. 63, the attachment means 146 comprises two rail clamp assemblies, each comprising a pair of opposing rail clamps 124a, 124b and a drawbar 127 coupled to the riser assembly F′ that are configured to engage with the accessory rail D to detachably secure the riser assembly F′ to the accessory rail D in the weapon system A′. In embodiments, rail clamps 124a, b are adapted to securely engage with Picatinny rails or the like included in accessory rail D.

[0117] In certain embodiments, each rail clamp assembly on the riser assembly F′ includes a drawbar 127 extending laterally between opposing rail clamps 124a, b. The drawbar 127 is configured to be received within a recoil transverse groove of the rail D, thereby preventing movement from weapon recoil. A rotatable thumbscrew 136 is threadedly engaged with the drawbar 127. In preferred embodiments, one of the rail clamps 124a, b is fixed in position in relation to the riser assembly F′ and the other is movable. As shown in FIG. 63, rail clamp 124a is fixed and rail clamp 124b is movable. Rotation of the thumbscrew 136 in a tightening direction draws the rail clamps 124a, b toward one another, urging them into clamping engagement with opposite lateral faces of the rail D. The engagement of the drawbar 127 within the recoil groove provides stability in the axial direction and prevents shifting under recoil forces. Rotation of the thumbscrew 136 in the opposite direction relieves the clamping force, allowing for removal or repositioning of the riser assembly F′. The thumbscrew 136 may include a knurled, slotted, or hex-head configuration for manual or tool-assisted operation.

[0118] The riser assembly F′ includes a main housing 10′, a lower surface 12′, and an upper surface 14′, which interfaces with the fire control system G. A front side 16′, rear side 18′, right side 20′, left side 22′ define a peripheral wall extending between the lower and upper surfaces 12′, 14′, respectively.

[0119] In the illustrated embodiment, the upper surface 14′ includes a recess 24′ and an electrical connector 26′, which extends through an aperture 66′ in the upper surface 14′. In embodiments, the recess 24′ engages with a complementary protrusion or boss (not shown) to ensure that the fire control system G is properly aligned when assembled to the riser assembly F′ and provides stability against movement or slippage under external forces or vibrations, such as recoil forces generated when the weapon A′ is fired. In the illustrated embodiment, the upper surface 14′ is configured as a cover plate secured to the peripheral wall via a plurality of threaded fasteners (not shown) engaging clearance openings 15′ in the upper surface 14′ and threadably engaging aligned openings 17′ in the upstanding wall defined by the front side 16′, rear side 18′, right side 20′, and left side 22′. Threaded fasteners (not shown) engage clearance openings 19′ in the side walls 20′, 22′ and threadably engage aligned openings 21′ in the upper plate 14′.

[0120] The right housing side 20′ includes an aperture 28′ for receiving a right side battery tube 30′, which in turn houses a right battery 32′. The left housing side 22′ includes an aperture 34′ for receiving a left side battery tube 36′, which in turn houses a left battery 38′. Each of the battery tubes 30′, 36′ has a removable battery cap 40′, 42′, respectively, to allow access to the batteries 32′, 38′ for removal and replacement when they run out of power. Although not shown, it is understood that aperture 28′, right battery 32′, aperture 34′, and left battery 38′ are similar to aperture 28, right battery 32, aperture 34, and left battery 38, as shown in FIG. 17.

[0121] In embodiments, the lower and upper surfaces 12′, 14′ are configured as removable plates covering an interior compartment 48′ housing a riser circuit assembly 50′. The riser circuit assembly 50′ includes a circuit substrate 62′, preferably a flexible circuit substrate, having the upper connector 26′ thereon. The riser circuit assembly 50′ also includes circuit assembly plate 144, which acts as a backstop or position-holder for camera 134, as discussed below. The riser circuit assembly 50′ also includes a switch assembly 64′. The switch assembly 64′ comprises an actuator knob 68′ and a 3-position rotary switch 70′. The switch 70′ is operable to provide distinct electrical pathways corresponding to a left or “L” position which couples the riser circuit assembly 50′ to the left battery 38′; a right or “R” position which couples the riser circuit assembly 50′ to the right battery 32′, or a “battery off” position which disengages or isolates both power sources 32′, 38′ to prevent unintentional operation. In embodiments, markings or indicators 72′ representative of the selected position are provided on the housing 10′.

[0122] In certain embodiments, the circuitry on the riser circuit assembly 50′ includes one or more capacitors (not shown) for storing electrical energy to act as a temporary power supply for brief periods to ensure that power to the connector 26′ is not interrupted when switching between the left and right batteries 38′, 32′. This is particularly advantageous when an attached fire control system G is a processor-based device that requires a reboot after power is lost or cycled. In certain embodiments, each battery 32′, 38′ is individually swappable such that when one battery is depleted it can be changed without affecting the operation of the devices being powered by the other battery.

[0123] The fire control system G includes an electrical connector 74 (see FIG. 45) which mates with the electrical connector 26′ on the riser assembly upper surface 14′.

[0124] The camera assembly 126 is forward-facing, i.e., it faces the same direction that weapon A′ is being aimed. As camera assembly 126 is disposed directly beneath fire control system G, exemplary embodiments of which include aiming mechanisms, as discussed above, camera assembly 126 is well positioned to visually record that at which the weapon A′ is being aimed. Camera assembly 126 adds functionality to the otherwise unused space of the riser block.

[0125] Camera assembly 126 images a scene within the field of view of the camera assembly 126. The camera assembly 126 includes a lens 130 assembly to capture video footage and a sensor array (e.g., a charge-coupled device (CCD) array or a complementary metal-oxide-semiconductor (CMOS) array) for converting incoming light into electrical signals and a processing unit for storing digital representations of an imaged scene as would be understood by persons skilled in the art. The camera assembly 126 may be configured to record and / or transmit still images, video images, or both. The camera assembly 126 is powered by the batteries 32′, 38′.

[0126] The lens 130 is held in place between the outer lens frame 128 and the housing lens frame 132, which is an aperture through the housing front side 16′. The actual camera 134 is disposed within interior compartment 48′, just behind lens 130.

[0127] The camera 134 is held in place within interior compartment 48′ in part by circuit assembly plate 144, which holds camera 134 toward the front of the interior compartment 48′ in position with lens 130 and keeps camera 134 from physically interfering with the operations of riser circuit assembly 50′.

[0128] In embodiments, a wireless communication module 138, including an antenna and associated transmitter or transceiver, is in electrical and data communication with the camera 134 and has wireless data communication capabilities such that antenna module 138 is capable of transmitting video or other images recorded by camera 134 to a remote location. In embodiments, the wireless communication module 138 is configured to transfer image data acquired by the camera 134 to an external device. The module may support one or more wireless protocols, such as Wi-Fi, Bluetooth, or other short-range or network-based communication standards, including but not limited 5G, 4G, and intra-soldier wireless (IWS) network standards. The image data may be stored temporarily in onboard non-removable memory and transmitted wirelessly either in real time (e.g., streaming) or in batch after acquisition.

[0129] In certain embodiments, a card reader 140 is in electrical and data communication with camera 134. The card reader 140 interfaces with a computer readable storage medium, such as a removable flash memory card 142 for digitally storing video or other images recorded by camera 134.

[0130] In an alternative embodiment, the camera assembly 126 includes a non-removable computer-readable storage medium, such as onboard flash memory, configured to store digital image data acquired by the camera 134. The stored data may be accessed and transferred via a data port (not shown) provided on the accessory housing. The data port may include, for example, a USB interface or other wired digital communication interface, enabling transfer of stored image files to an external device such as a computer, storage drive, or networked system for review, processing, or archival purposes.

[0131] In certain embodiments, the riser assembly F′ appearing in FIGS. 47-53 which includes the integral camera assembly 126 and which is adapted for mounting to a rail D which may be a conventional Picatinny rail may be modified for compatibility with the handguard and accessory rail system of the type appearing in FIGS. 1-7 and 7A, such as a WILCOX FUSION® handguard (Wilcox Industries Corp., Newington, New Hampshire), thereby yielding a further embodiment riser assembly as shown in FIGS. 1-7, 7A, and 8-18 but which further incorporates the integral camera assembly 126 as shown in FIGS. 47-53. Conversely, the riser assembly F appearing in FIGS. 1-7, 7A, and 8-17, which lacks the integrated camera feature in the riser assembly, may likewise be adapted for attachment to a conventional Picatinny rail by employing the rail attachment means as shown and described in connection with the embodiment illustrated in FIGS. 47-53, thereby providing a still further embodiment capable of integration with widely available standardized mounting systems. Such modifications may include, without limitation, alterations to the mounting interface while retaining the core functional features of the respective embodiments.

[0132] Referring now to FIGS. 54 and 55, there is shown a further embodiment of a firearm and weapon system similar to that shown in FIGS. 1-7. The differences are most apparent in a side-by-side comparison of riser assembly F″ in FIGS. 54 and 55 with riser assembly F in FIGS. 2 and 4, respectively. As shown in FIGS. 2 and 4, a riser assembly F″ is secured to the weapon accessory interface, e.g., using threaded fasteners or the like. Unlike in FIGS. 2 and 4, no fire control system G is secured to the riser assembly F″. Instead, the upper surface 14 of riser assembly F″ includes an additional non-powered accessory rail segment 200 adapted for the attachment of an accessory device. In embodiments, the rail segment 200 is a standard Picatinny rail. Exemplary accessory devices that may be attached at the rail segment 200 include, but are not limited to, reflex sights, red dot sights, laser sights, holographic sights, night vision scopes, thermal imaging scopes, digital rifle scopes, and the like. The riser assembly F″ lacks upper connector 26 for connection with fire control system G and is not configured to transmit electrical power to an attached accessory device. Similar to the riser assembly F, the riser assembly F″ contains the batteries 32, 38 that power, e.g., keypad assembly H, flashlight assembly I, and other accessories disposed on the handguard, as discussed above.

[0133] Referring now to FIG. 56, an exploded view of a shorter version of the firearm and weapon system is provided, including a camera system 126 in the riser assembly F′″. Comparing FIG. 56 with FIG. 17, weapon A′ has a shorter barrel. Otherwise, similar to the system shown in FIG. 17, the system shown in FIG. 56 also includes hand guard circuit assembly 80 and circuit substrate 82 within handguard assembly B, keypad assembly H, and flashlight assembly I. Fire control system G is also included, but the system shown in FIG. 56 includes fire control system G attached to the riser assembly F′″ including camera assembly 126, as described above with reference to FIGS. 47-53.

[0134] Referring now to FIG. 57, an exploded view of the riser assembly F′″ with a camera system 126 appearing in FIG. 56, which is intended for direct mounting with the handguard. Riser assembly F′″ is similar to riser assembly F′, shown, e.g., in FIG. 53. They differ in that riser assembly F′ attaches to the handguard / rail system through rail clamp assemblies, including rail clamps 124a and 124b and riser assembly F′″ attaches to the handguard / rail system through other attachment means, such as bolts (not shown).

[0135] Referring now to FIGS. 58 and 59, isometric and exploded views, respectively, of a camera assembly J configured to couple to a handrail accessory interface slot are provided. The camera assembly J has a similar housing and attachment as flashlight assembly I, as described with reference to FIG. 29. The camera assembly J includes a head portion 123 and a body portion 125. Although not shown in FIGS. 58 and 58, in embodiments, the camera assembly J is configured similarly to the flashlight assembly I as shown in FIG. 29 to plug into a common point 100 on the handguard assembly B via a plug 98, and is powered by the power sources 32, 36 within the riser assembly F or F′. In embodiments, the camera assembly J does not contain a battery. This allows the camera assembly J to be as compact as possible.

[0136] The camera assembly J includes camera 202, camera plate 204, lens 208, and camera outer frame 210. The camera outer frame 210 is disposed at the head portion 123 of the camera assembly J and includes an opening 211 through which the camera 202 may “look.” The lens 208 is disposed and held within the opening 211. The camera 202 is disposed directly behind the lens 208 and is held within the head portion 123 of the camera assembly J thereby. The camera plate 204 is disposed behind the camera 202 and acts as a backstop to hold the camera 202 in place.

[0137] Camera 202 images a scene within the field of view of the camera assembly J. In embodiments, the camera 202 is configured to capture video footage and a sensor array (e.g., a charge-coupled device (CCD) array or a complementary metal-oxide-semiconductor (CMOS) array) for converting incoming light into electrical signals and a processing unit for storing digital representations of an imaged scene as would be understood by persons skilled in the art. In embodiments, the camera 202 is be configured to record and / or transmit still images, video images, or both.

[0138] The body portion 125 of camera assembly J is coupled to the connector assembly 97 attachable to a handguard interface assembly 95 via threaded fasteners 93. The connector assembly 97 is advantageously an M-LOK compatible connector. The cable 96′ is preferably relatively short and flexible, with sufficient length to allow the camera assembly J to be positioned at any point on the perimeter of the handguard assembly B. In embodiments, the power routing to the camera assembly J is done completely inside the handguard assembly B with no exposed cables.

[0139] In embodiments, the connector assembly 97 is disposed within the interior of the handguard assembly B and includes an upstanding boss 49′. The threaded fasteners 93 pass through aligned clearance openings 51′ in the body portion 125 threadably engage openings 53′ in the connector assembly 97. The fasteners 93 provide a clamping force between the camera assembly J and the connector assembly 97 to secure the camera assembly J to the handguard assembly B. The electrical connector 55′ is disposed on the boss 49′ and engages a complementary connector (not shown) on the body portion 125 for electrically coupling the camera assembly J to the handguard assembly B.

[0140] Referring now to FIGS. 60-61, and with continued reference to FIGS. 18-26, isometric views of the muzzle end of the weapon of the firearm and weapon system are provided, showing the flashlight assembly I attached to a handguard interface slot, with the remote keypad assembly housing absent and present, respectively. In FIG. 59, remote keypad assembly H is absent. Instead, switches 119a-d are operably and electrically coupled to the handguard circuit assembly 80 to communicate input and commands from the user. In FIG. 60, the keypad assembly H of FIG. 20 is shown in place on the muzzle of weapon A or A′.

[0141] Referring now to FIGS. 62-65, views of the firearm and weapon system are provided, including an integration of the fire control system G and the riser assembly F′ including the camera system 126. This system is similar to that described above with reference to FIGS. 47-53, but instead of the fire control system G being removably attachable to the riser assembly F′, the two components are a single integrated unit.

[0142] The invention has been described with reference to the preferred embodiment. Modifications and alterations will occur to others upon a reading and understanding of the preceding detailed description. It is intended that the invention be construed as including all such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
