Battle Arms Development THUMPER Muzzle Device .30 Cal – AR-15/AR-10 Platform Rifles

The Battle Arms Development THUMPER muzzle device is a precision-machined brake designed to reduce recoil and muzzle rise on .30 caliber rifles. Its directional port design redirects gases to control muzzle climb during rapid fire, helping shooters maintain sight picture and target tracking. This is a practical solution for competitive shooters and precision rifle enthusiasts who need fast follow-up shots without excess felt recoil.

The THUMPER is CNC-machined from steel with a black nitride finish for corrosion resistance and durability. It installs on standard 5/8x24 TPI threaded barrels common to .30 caliber AR-pattern rifles and bolt guns. A crush washer or shim kit (not included) is recommended for proper timing. Compatible with AR-15 rifles in .300 Blackout, AR-10 rifles in .308 Winchester/7.62 NATO, and other firearms with matching thread pitch and caliber.
