Muzzle brakes (not breaks) are designed to reduce the overall felt recoil of a rifle. Muzzle brakes work in one of two ways, they either redirect or deflect the gases. When you fire a gun, the gun powder turns into gas and the propels the projectile down the barrel. As the gas reaches the muzzle brake, it hits a wall inside the brake, and this wall diverts gas out the side of the brake.

The gas hitting the wall of the muzzle brake slightly shifts the weapon forward. This is where your recoil reduction is felt. You don’t feel this forward movement because the rearward recoil is still in play. Most AR-15 calibers do not have substantial recoil, but there is enough recoil to cause movement with the weapon.

The muzzle brake helps eliminate this movement and like a compensator makes it easy to get back on target. Some calibers benefit more from a muzzle brake than others. Big bore calibers like the 450 Bushmaster and 458 SOCOM are solid contenders for muzzle brakes due to their harsher recoil.

    Reduces recoil of my 450 Bushmaster by 1/3 to 1/2 depending on load. Helped with accuracy too. I went from .75 to .5-.6
