The Battle Arms Thumper Muzzle Brake, .223/5.56, 1/2×28, Black Nitride (Battle Arms Development part number BAD-THUMPER-223-BN) is a muzzle brake built to control recoil and muzzle rise on .223 Remington/5.56 NATO AR-15s. Battle Arms Development designs the Thumper line to keep the muzzle as flat and stable as possible under recoil, reducing felt recoil and muzzle flip for faster, more accurate follow-up shots. Threaded 1/2×28, it fits the standard thread pattern found on most 5.56 AR-15 barrels. Finished in black nitride, it adds corrosion resistance while matching the black finish common on most AR-15 builds.
