The result is better accuracy so long as you have good shooting skills. That process keeps the barrel closer to “true” on your target and allows the shooter to quickly adjust their aim and fire again. Because a muzzle brake helps to control and redirect the flow of gas as the bullet leaves the barrel, it helps to reduce bounce or wobble. Generally, the more powerful the round the more the bounce or wobble. Some types of guns have more bounce or wobble than others do. It also can push the barrel downward to counter the upward barrel movement after the round exits the barrel.Ģ.Improves accuracy – When you fire a bullet, gas is released from the burning of powder and a rapid increase of pressure causes the barrel of the gun to bounce or wobble. As the pathway of pressurized gas moves sideways and upwards, it decreases the backward push or recoil of the gun. That process occurs because a muzzle brake allows pressurized gas to escape sideways and when vented on the top, to move upwards. Benefits of a Muzzle Brakeġ.Reduced recoil – The biggest benefit of fitting your gun with a muzzle brake is to reduce recoil. Also, some shotgun barrels are not thick enough to cut threads for mounting a muzzle brake. However, a muzzle brake for a shotgun would need to be designed to not affect the blast pattern of the shot. There are muzzle brakes for pistols and the theory of what a muzzle brake does could be applied to a shotgun. Some people think of rifles as having muzzles and handguns as having barrels, but the reality is that the terms can be interchanged. The same device used on a pistol is referred to as a “compensator”. Weapons that Use a Muzzle BrakeĪ muzzle brake is used on rifles and generally on semi-automatic rifles such as an AR-15. In military combat scenarios, they add another benefit by lowering the likelihood of compromising one’s position in the dark. Flash guards are beneficial to shooters in low light conditions as they prevent the shooter’s vision from being obscured by bright light. A silencer may help or hinder accuracy.Ī muzzle brake also differs from a flash suppressor, flash guard or flash hider in that the brake provides recoil reduction on a weapon while the flash suppressor reduces the visual flash from firing a weapon. A muzzle brake is different from a silencer in that (1) a muzzle brake does not make your shot quiet – it is quite loud, (2) the movement of propellant gases are to the side or upwards with a muzzle brake whereas the gas tends to move forward with a silencer, and (3) muzzle brakes help to improve accuracy by diminishing muzzle movement during firing. It is designed to allow pressurized gas to escape the barrel in a sideways or upwards motion. Definition of a Muzzle BrakeĪ muzzle brake is a muzzle device that’s an add-on or upgrade to a barrel or muzzle. The process reduces the recoil of the gun to improve shooter accuracy by stabilizing barrel movement. A muzzle brake also has vents along the side and top, which allow the pressurized gas to escape upwards and to the side. Gun powder, when ignited, creates high pressure gas that pushes backward on the rifle as the bullet moves forward when you fire a round. A muzzle brake helps to diminish the felt recoil or reactionary force produced by the “action” or firing of the round. There is also a reaction – the recoil or the forcing of the gun backward. When you fire a bullet, it creates an action – the propelling of the projectile forward. It’s part of Newton’s third law of gravity which states, “that for every action there must be an equal opposite reaction.” For the bullet to move forward an equal pressure must push backward – that process is called recoiling. When a round has fired, the gas produced by the burning of powder pushes the gun backward. Their job is to redirect the flow of combustion gases after a round is fired. They can be applied to either a rifle or pistol but are commonly fitted to assault rifles. These are typically small tubular devices that attach to the tip of the barrel or muzzle. What is a Muzzle Brake?Ī muzzle brake is also called a recoil compensator. This blog post discusses and defines a muzzle brake, what it does, and why it can be a good add-on to your AR-15 or other guns. If you are wondering what a muzzle brake is used for, you are in the right spot.
