Muzzle brakes and recoil compensators are devices that are fitted to the muzzle of a firearm or cannon to redirect propellant gases with the effect of countering both recoil of the gun and unwanted rising of the barrel during rapid fire[1]. Muzzle brakes are very useful for combat and timed competition shooting, and are commonly found on rifles firing very large cartridges (often big-game rifles), as well as some artillery and tank guns. They are also commonly used on pistols for practical pistol competitions, and are usually called compensators in this context[2].

Terminology

The term muzzle brake was introduced in the context of artillery, but it is can be used for rifles and pistols. It defines a device that reduces the recoil weapon by directing the propellant gases backwards. The force generated at the muzzle brake baffles or ejector ports acts in the opposite direction to the force of recoil, thus reducing wear on the recoil-damping mechanism and allowing a lighter design. In case of smaller-calibre firearms like rifles it reduces the effects of kickback on the shooter.

The terms recoil brake and recoil check are seldom used and never in artillery parlance. The terms recoil compensator, compensator, Mag-na-port and others belong to shooters' lingo and refer to devices that serve to direct propellant gases upwards to reduce muzzle climb and to some extent also the recoil in hand firearms like pistols and revolvers, and also in small-calibre automatic weapons like assault rifles, PDWs etc. With the exception of names for proprietary systems, such as Mag-na-porting and hybrid compensators, and brand names such as Muzzle Tamer, the various terms in the hand firearm parlance are used interchangeably.[3][4][5][6][7][8][9][10]
