A camera integrated firearm system replaces the original recoil spring and guide assembly of a firearm with a casing which includes a camera, a camera actuating module which turns the camera on when the orientation of the handgun barrel is changed, a gunshot impact sensing and signal transmitting module, an image memory module, and output data ports. The casing is also equipped with a unique power-data port integrated into the lens unit of the camera. When the weapon is drawn, the camera is turned on to record events, including the discharge of the weapon. The camera, utilizing ambient light plus the light generated by muzzle flash, i.e. the jet of fire exiting the barrel at the instant the bullet exits the weapon, takes and saves, in memory, a closely spaced sequential stream of digital photographs or, alternatively, video recordings. Using the data outputs, the images can then be downloaded for viewing.

A flash suppressor of the open prong type having a twist in its structure formed of alternating grooves and flutes or prongs provides a highly effective flash suppression for small and medium caliber weapons and especially for automatic weapons and machine guns when placed on the end of their barrels. The orientation of the direction of the twist of the structure is in a direction opposite to the direction of the rifling in its firearm barrel. Various objective laboratory tests and subjective user evaluation on its performance prove out its effectiveness in terms of mitigating visible flash on shorten machine gun barrels as well as standard full length barrels used in critical helicopter black out operations using night vision equipment. In addition, precise aiming of a weapon equipped with the inventive flash suppressor exhibits lower dispersion of actual projectile impact compared to conventional flash suppressors.

A camera integrated firearm system replaces the original recoil spring and guide assembly of a firearm with a casing which includes a camera, a gunshot impact sensing and switching module, an image memory module, and output data ports. When the weapon is discharged, the sensing and switching module senses this discharge and immediately turns on the camera. The camera, utilizing ambient light plus the light generated by muzzle flash, i.e. the jet of fire exiting the barrel at the instant the bullet exits the weapon, takes and saves, in memory, a closely spaced sequential stream of digital photographs or, alternatively, video recordings. Using the data outputs, the images can then be downloaded for viewing.

The invention relates to rifled and smoothbore firearms and can be used in barrel-mounted devices for firing in the air and in the water. The inventive barrel-mounted device for firearms comprises a unit for joining to the barrel, a cap and a starting part with gas vents. The starting part bore is the continuation of the barrel bore, and there are N≧1 compartments formed between the casing and the starting part. Each compartment includes at least two gas vents and provides the possibility of gas exhaust from the starting part bore to the compartment through the first of the mentioned gas vents and gas exhaust from the compartment to the starting part bore through the second gas vent. The compartment length is 0.5-3.0 of the bore caliber and in the cross-section plane of the barrel-mounted device the minimal cross-section area of N≧1 compartments, designed for the gas flow between gas vents, ranges within 0.4-4.5 of the barrel bore area. The barrel-mounted device can comprise a muzzle compartment, which projects beyond the muzzle face of the starting part and has a front wall with a muzzle opening. The diameter of the muzzle opening equals to 1.05-1.2 of the barrel bore caliber. The said invention makes it possible to reduce recoil momentum, shot blast and muzzle flash while firing in the air, as well as to reduce recoil momentum and hydraulic impact in the course of underwater firing.

A flash redirecting recoil compensator for a firearm includes a compensator body that provides a platform for the rest of the components. The compensator body attaches with a firearm in order to reduce recoil force and redirect the muzzle flash away from the site of the shooter. An attachment chamber and a discharge chamber of the compensator body are positioned through a top portion of the compensator body from a rear face to a front face. The attachment chamber fastens the compensator body into the firearm while the discharge chamber provides space for the discharging bullet. At least two vectoring ports, which are traversed through the compensator body and into the discharge chamber, redirect hot gas and unspent propellants away from the firearm after the bullet is discharged as the redirection of the hot gas and unspent propellants reduce the recoil force and provide a clear shooting sight.
