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.
The FG 42 used a fairly sophisticated muzzle device that did help with recoil and muzzle flash, but made blast and noise much greater than on other similar weapons. The US M14 rifle had similar problems, and attempts were made to upgrade that rifle the same way with an in-line stock and muzzle device.
Failure to feed (FTF) is when a firearm fails to feed the next round into the firing chamber. Failure to feed is common when the shooter does not hold the firearm firmly (known as limp wristing), when the slide is not fully cycled by the preceding round, or due to problems with the magazine. It can also be caused by worn recoil springs, buffer ...
Gun with threaded muzzle besides a disassembled muzzle brake and thread protector. Muzzle threads is one method of fitting accessories such as flash hiders, suppressors or muzzle brakes (compensators). The applicable thread is limited to a certain degree by the bullet caliber and barrel diameter.

Animation of the Vickers muzzle booster operation, showing the expanding gases pushing the barrel to the rear relative to the cooling jacket. A Vickers-type muzzle (or recoil) booster, the "typical" type, consists of two parts: a flared "cup" on the muzzle of the barrel, and a perforated tube around the end of the muzzle, attached to the main body of the weapon.
Other muzzle devices such as blast shields can also protect hearing by deflecting the pressure wave forward and away from the shooter and bystanders. Recoil-reducing devices such as muzzle brakes however worsen potential hearing damage, as these modulate the muzzle blast by increasing the lateral vectors nearer to the shooter.
Daewoo USAS-12 automatic shotgun. An automatic shotgun is an automatic firearm that fires shotgun shells (thereby making it a shotgun) and uses some of the energy of each shot to automatically cycle the action and load a new round. [1]
