Battle Arms Development Thumper Muzzle Brake .22 Caliber 1/2x28 – AR-15 & Compatible Rifles

The Battle Arms Development Thumper muzzle brake redirects propellant gases to reduce felt recoil and muzzle rise on .22 caliber rifles. Its compact single-chamber design provides noticeable recoil mitigation for fast follow-up shots without adding excessive length to the barrel. This brake is particularly effective on AR-15 platforms chambered in .223 Remington or 5.56 NATO, where managing muzzle climb improves accuracy during rapid strings of fire.

The Thumper features a 1/2x28 thread pitch, the standard threading for .22 caliber centerfire rifles including most AR-15 barrels. Constructed from steel with a black nitride finish, it resists corrosion and wear while maintaining a low-profile appearance. Installation requires a crush washer or shim kit (not included) to properly time the brake, and a standard armorer's wrench or muzzle device tool. This brake adds minimal weight and does not require modification to existing barrels.
