Steel construction and recoil reduction

The Thumper muzzle brake uses stainless steel construction to withstand high-temperature cycling and corrosive environments. Its ported design redirects expanding gases to counteract muzzle rise, helping shooters maintain sight picture during rapid fire. This brake works with .223 REM and 5.56 NATO ammunition. Before installing any muzzle device, confirm your local regulations. Our team at TacticCAL can walk you through options—check our California gun-buyer FAQ for common questions.
