Originally limited to "special purpose" roles, it was now expected that all infantry weapons with shorter barrels would experience this problem, and thereby be of limited use in low-light situations. When barrel lengths were dramatically decreased with the introduction of various shorter-barreled rifles and carbines, the flash became a serious problem during night-time combat, as the flash would impair the shooter's night vision and would also make the shooter's position more apparent. However, if the same weapon's barrel is "cut down" (shortened), as is common in cavalry and jungle-combat adapted versions, the bullet would often leave the barrel before the powder was completely consumed, resulting in a bright flash from the muzzle. A beneficial side effect of the long barrel is that the propellant is completely burned before the bullet leaves the barrel, usually resulting only in a puff of smoke from the muzzle. Pre-20th century rifle designs tended to have longer barrels than modern rifles. While the former is intended to reduce visible flash, a muzzle brake is designed to reduce recoil inherent to large cartridges and typically does not reduce visible flash. Ī flash suppressor is different from a muzzle brake, although they are typically mounted in the same position and sometimes confused with each other. Contrary to popular belief, it is only a minor secondary benefit if a flash suppressor reduces the intensity of the flash visible to the enemy. Its primary intent is to reduce the chances that the shooter will be blinded in low-light shooting conditions. Detail of the birdcage-type flash suppressor on a SIG SG 550Ī flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a muzzle device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Schlieren imaging reveals the heat and pressure gradients invisible to standard imaging. Ultra small we recommend using crush washer.Exhaust gas light-dimming gunbarrel attachment Bullet exiting an A2-style flash suppressor, photographed with a high-speed air-gap flash This image was taken from a high-speed Schlieren video of a flash suppressor. A2 we recommend peel washer or crush washer. 3 prong and Early A1 recommend Lock washer. as above, but slightly longerįor washer (Here). Can be pinned to effectively remove threads from a barrel with minimal increase in size or weight. Cosmetic side holes makes this a barrel extender only. (one of our favorite muzzle devices for all modern rifle builds) Looks like the standard M16A2 / M4 flash hider used today, but has a closed end making this more a muzzle brake instead. Slots on sides do not go all the way through, making this just a muzzle extender.
Slots on side go all the way through and are function. Turns the function of the M16A1 flash suppressor into a muzzle brake instead by closing off the front end. Fake slots on side as they do not go all the way through turning the original 3 prong flash hider into a muzzle extender only.
These muzzle devices are designed and manufactured by Retro Rifles specifically to pass the "Pinky test" in states such as New York, New Jersey, California, Etc.
