The AR-15 muzzle brake is a muzzle device that reduces felt recoil and muzzle rise by redirecting gases as the rifle fires. It threads onto standard 1/2×28 threaded AR-15 barrels and works with mil-spec upper receivers and handguards. Shooters use the muzzle brake to get faster follow-up shots and better muzzle control during rapid fire. Builders choose it as an upgrade over a standard flash hider for tactical, competition, and recreational AR-15 builds.
