Battle Arms Development THUMPER Muzzle Brake .22 Cal 1/2x28 – AR-15 & Bolt-Action Rifles

The Battle Arms Development THUMPER muzzle brake is designed to reduce felt recoil and muzzle rise on .22 caliber rifles, improving control during rapid strings of fire and precision shooting. Its multi-port design redirects gas to counteract climb and keep the muzzle flat, particularly beneficial for lightweight AR-15 builds or high-volume training sessions where fatigue management matters.

Machined from stainless steel with a natural finish, this brake threads directly onto standard 1/2x28 barrels common to .223/5.56 AR-15 platforms and many bolt-action .22 centerfire rifles. Installation is straightforward with a crush washer or timing shims to achieve proper alignment. No gunsmithing required for most applications.
