A firearm bolt locking mechanism includes a locking pin in the bolt carrier of a firearm like an AK-47 assault rifle or variant thereof. The locking pin is normally urged from the bolt carrier by a compressed spring. The mechanism also includes a pivot arm mounted on the receiver cover of the firearm. The pivot arm has a spring-biased finger that normally fills a hole in the receiver cover. The mechanism further includes a magazine that stops the bolt of the firearm when the last cartridge from the magazine is fired and permits the spring to drive the locking pin into the hole. After replacing the empty magazine with a full one, the pivot arm is pressed to replace the locking pin in the hole with the finger and to release the bolt carrier to chamber a cartridge.

The present folding stock adapter can be used with many types of military-type assault rifles that typically comprise a receiver extension, buffer and action spring. The present folding stock adapter can be used to add a folding capability to a standard stock allowing it to fold against a rifle's receiver when the weapon is not in use, thus reducing the overall length of the weapon. This reduction in length can facilitate its maneuverability, storage and transport in cramped quarters. The present device can also allow for the quick unfolding of the stock in order to allow the weapon to function and be fire normally.

Systems and methods for carrying a weapon are described herein. While such systems and methods can include any suitable component, in some cases, they include a shoulder strap that is configured to attach at a shoulder portion of an upper torso garment. In some cases, the shoulder strap includes an attachment mechanism that is configured to attach the shoulder strap to the shoulder portion of the upper torso garment. In some cases, a weapon attachment, such as a D-ring and/or a lanyard is attached to the shoulder strap so as to be disposed on an anterior portion of the shoulder strap when the shoulder strap is worn by a user. In some cases, the shoulder strap is configured to retain a weapon (such as an assault rifle) in a state of near readiness. Other implementations are described.

Back-up sights for use on a rifle configured with an optical sight aligned along a first sighting axis include a handguard or support carrying first and second attachment points that are substantially parallel with the central axis of the rifle's barrel but offset at a different angle than the first sighting axis. A back-up front sight and rear sight are carried on a back-up sight base, where the front sight and rear sight are aligned along a second sight axis that is offset, preferably, by one-eighth turn from the first sighting axis. When using the back-up sights, the user tilts or cants the rifle to one side, rotating the rifle one-eighth turn about the axis of the barrel's bore, to look down the second sighting axis, while aiming the rifle at the target.

The wireless video game controller is a 1:1 scale realistic replica Air soft gun, of a weapon, such as a US military standard issue assault rifle or machine gun. An M16, M4, or other such realistic replica having realistically operational moving mechanical parts may function as a wireless video game controller when equipped with a wireless video game controller having switch placement that facilitates electrical and mechanical interaction between the switches and the operational moving mechanical parts of the gun replica. Moreover, joystick and pushbutton wireless game controls are disposed on portions of the gun that are ergonomically consistent with a gun user's stance and hand positioning when handling and firing the weapon. Programmable buttons are optionally provided and placement of the programmable buttons is consistent with the inventive game controller's ergonomic design.

A shooting crossbow includes two cams, two pulleys, a bow string, two cables, a string latch housing, a bow riser, a mainframe barrel and two limbs. The bow riser is enjoined with the barrel. The first and second limbs extend from the bow riser. First and second cams are pivotally retained on first and second limbs. The first and second cams retain a bowstring. The cams and pulleys retain first and second cables. The two pulleys are retained on the barrel. The mainframe barrel combines elements of an AR style butt stock mounting tube, and flight deck elements of a crossbow barrel extrusion.

A buffer tube for firearms, including assault rifles, carbines, shotguns, and other rifles is disclosed. The floating buffer tube comprises a recoil mitigation mechanism, including a helical spring or an elastic or viscous energy absorption device, and a buttstock mounting bracket mounted outside the buffer tube. The buttstock mounting bracket can rotate relative to the buffer tube, which changes the axial angle of the buttstock relative to the firearm. The angle can be locked under an expansive force by forcing a bolt or pin into grooves to select the proper axial angle of the buttstock relative to the firearm in the field without the user having to disarm himself to perform the angle change.

The invention is directed toward a magnetized takedown tool for removing pins from an assault rifle. The magnetic element of the magnetized takedown tool allows the tool to be removably secured to an assault rifle. In addition, the invention is directed toward a docking unit which may be removably secured to the assault rifle and to which the magnetized takedown tool can be removably secured during use.

The present invention is directed toward a firearm takedown assembly. The preferred embodiment of the firearm takedown assembly comprises a docking plate configured to be removably secured to a firearm and a lever pivotably attached to the docking plate. The assembly may further comprise a pivot pin, wherein the lever is connected to the pivot pin. The lever is utilized to remove a takedown pin from the upper and lower receiver of the firearm so that a user may quickly disassembly the firearm. When the user desires to reassembly the user may thumb the lever to reinsert the takedown pin into the upper and lower receiver.

Converting a functioning assault rifle to an inoperative dummy gun suitable for collectors by replacing the receiver with a receiver filled with a solid material. The filled spaces of the receiver prevent the cooperative operation with the other components of the gun. The dummy receiver is externally indistinguishable from the functioning receiver. Thus, a model rifle is converted for collectors so as to be unrecognizable from the functioning gun. To accommodate the filled spaces in the receiver, the lower part of the cooperating bolt carrier is milled off. The dummy receiver may include an affixed rear sight base.

A method for tracking extremely dangerous weapons, such as assault rifles, is described. This method comprises of a GPS device which is strapped onto the weapon, such as the assault rifle's neck. The position of the GPS, along with the location of the weapon is constantly monitored. If the position of the GPS and weapon is near a school, an alarm signal is sent to a Global Position Processing Center. The Center then immediately contact and inform the school and the local police department about the position of the weapon by its GPS positional signal. If the GPS is disabled, an alarm signal is sent to the Center. The Center then investigates the reason for its disablement. If the disablement of the GPS is illegal, then the Center will contact the local police for further investigation of the weapon. In this way, dangerous weapons, such as assault rifles, are kept track of and schools are alerted when such weapons come within its safety perimeter. By this method, law enforcement agencies can pursue missing weapons and account for all dangerous weapons and their locations.

A semi-automatic sporting rifle is created by the modification of a fully automatic assault rifle Sa vz. 58. The semi-automatic rifle is constructed partly from original parts of the Sa vz. 58 assault rifle, i.e. bolt carrier, locking piece, striker, return mechanism, barrel, trigger, interrupter and left hand side striker catch, partly from modified parts of Sa vz. 58 assault rifle, i.e. bolt, trigger mechanism feather and safety catch and partly from newly manufactured parts, i.e. semi-automatic receiver with a narrowed magazine well for a single stack removable magazine with extended bridge, safety catch with one more groove on its lower left hand side, new sporting stock where grip part and butt-stock part form one unit and barrel extension permanently attached to the muzzle. Some parts of the Sa vz. 58 assault rifle are removed completely, i.e. muzzle thread protector, bayonet lug, original receiver, original stock, pistol grip, release, lever, trigger lever and right hand side striker catch. In a second version, an inseparable, double stack magazine box is used.

A firearm receiver with an extended bridge is created to prevent the fully automatic fire of an assault rifle. The extended bridge receiver has a narrowed magazine well for a single stack removable magazine, safety catch with one or more grooves on its lower left hand side, new sporting stock where grip part and butt-stock part form one unit and barrel extension permanently attached to the muzzle. The receiver can be configured with a rivet on the bridge in a location that prevents backward turning of the safety catch, where the modified safety catch has two positions (i.e. safe and fire), rather than the three positions consistent with a fully automatic firearm. In a second version, the extended bridge lacks a release lever groove. In yet another version, an inseparable, double stack magazine box is used.
