Muzzle flash is the visible light of a muzzle blast, which expels high-temperature, high-pressure gases from the muzzle of a firearm. The blast and flash are caused by the combustion products of the gunpowder, and any remaining unburned powder, mixing with the ambient air. The size and shape of the muzzle flash is dependent on the type of ammunition being used and the individual characteristics of firearm and any devices attached to the muzzle (such as a muzzle brake or flash suppressor).
Camera integrated firearm system and method
ActiveUS7937880B1Maintains the weapon's accuracy, safety, and reliabilitySafety arrangementCartridge extractorsCamera lensData port
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.

Gun Shot Detector
A gunshot detection system provides an audio and visual surveillance system, embodied within a Gunshot Detector (GSD) attached to a building's walls and ceilings and a Firearm Event Detector (FED) worn on a person's outer clothing. In both embodiments, the system of the invention detects the physical signatures of a firearm discharge, specifically sound from a muzzle blast and light from a muzzle flash. The system would be linked to a software program and / or electronic transducer(s) and / or microprocessor(s) and / or electronic Logic Circuitry (using algorithms, logic gates) that would apply one or more identification algorithms to distinguish firearm discharge from other signals. Either embodiment may be linked to an emergency notification system or to a “Guardian Barrier System” (GBS) wherein a facility or premises, for example a school, is equipped with electromagnetically releasable and electromagnetically lockable doors such that facility or premises may be automatically locked down.

Adjustable gas block for an indirect gas operated firearm
A firearm including a barrel, receiver, indirect gas system and an adjustable gas block Four positions of adjustment are provided for on the adjustable gas block, each of which provides a different setting to regulate gas flow into the host firearm's operating system. A position of adjustment is selected based on how the firearm is being used. The provided positions of adjustment are calibrated for the standard use of the host firearm, use of a silencer, use of the firearm under hard or adverse conditions or when it is necessary to increase the firearm's rate of fire, and to block the flow of gas into the operating system. The provided gas block is designed to function with an indirect gas operating system, but could be adapted for use with a direct gas impingement system as well. Excess gas from the operating system is not vented from the gas block thereby eliminating the generation of additional muzzle flash and sound. No tool is required to manipulate the adjustment mechanism of the gas block.

Muzzle flash suppressor
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.

Barrel-mounted device for a firearm
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.

Flash Redirecting Recoil Compensator
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.

Flash suppressing and recoil compensating muzzle device
A flash suppressing and recoil compensating muzzle device for use with a firearm provides a muzzle device that reduces recoil and inhibits muzzle flash while preventing audible harmonic resonant ringing after the firearm is discharged. The present invention accomplishes this through the use of an open ended muzzle device that redirects a portion of the high velocity gasses exiting the terminal end of the weapon through asymmetrically placed narrowing exhaust openings. The asymmetrically placed narrowing exhaust openings gradually direct exiting gases to the rear and to the sides of the muzzle in order to reduce recoil and reducing light emissions. The narrowing exhaust openings are formed by the radially positioned prongs of a distinct weight and width, which widen from the proximal to distal end of the muzzle device. The weight and mass disparity between prongs prevents audible ringing by reducing resonant vibrations between neighboring prongs.
