A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. [1] Barrels with an integral muzzle brake are often said to be ported.
A muzzle brake is designed to redirect the muzzle blast backwards, and therefore counter the recoil of the bullet. Muzzle brakes tend to be found on larger firearms, such as magnum rifles and artillery. A well designed muzzle brake can significantly reduce recoil, turning a rifle that would otherwise be punishing to shoot into a far more ...
Furthermore, recoil-operated firearm designs have moving barrels (e.g. most pistols or the Barrett M82 rifle). Muzzle threads are situated at the muzzle end of the barrel and can be used for mounting accessories such as a flash hider, suppressor or muzzle brake (compensator).
Sound suppressor: A muzzle mounted, detachable sound suppressor. Muzzle device: A compensator/muzzle brake compatible with the sound suppressor. Bipod: Tool-less detachment featuring cant and pan/track capability. Day optic: An Army specified variable power day optic and compatible rings. Back up sights: Iron sights offset 45 deg from the DOS.
For these reasons, the U.S. military declared the A2 flash suppressor as a compensator or a muzzle brake; but it is more commonly known as the "GI" or "A2" flash suppressor. [140] The M16's Vortex Flash Hider weighs 3 ounces, is 2.25 inches long, and does not require a lock washer to attach to the barrel. [172]
For instance, muzzle brakes primarily works by diverting some of the gas ejecta towards the sides, increasing the lateral blast intensity (hence louder to the sides) but reducing the thrust from the forward-projection (thus less recoil). Similarly, recoil compensators divert the gas ejecta mostly upwards to counteract the muzzle rise.
This muzzle device, described as a 'blast compensator', is a combination sound suppressor and muzzle brake, and is notable in its attempt at moderating the .50 BMG's muzzle blast and recoil, unlike contemporary large-caliber rifles, which are typically equipped with muzzle brakes only. Like the DSR-1, this rifle retains its bullpup ...
However, the AK-47's heavier weight and slower rate of fire do a good job of mitigating any disadvantage. In addition, newer AK-47-type rifles use a muzzle brake or compensator to reduce recoil. [127] Some AK-type rifles also have vertical foregrips to improve handling characteristics and to counter the effects of recoil. [149] [150]
