The MasterPiece Arms DN5 Muzzle Brake in 30 Cal is built for .308 Winchester and smaller cartridges that generate extra gas pressure and volume, including 7mm PRC and 7mm SAUM, from MasterPiece Arms (brand part no. DN5BRAKE-30). Machined from black nitrided, high-tensile steel and threaded at 5/8-24, it uses multiple angled blast ports to redirect propellant gas, cutting recoil and keeping the muzzle down between shots. In the company’s own testing, the design reduced recoil by 63%, and the upward gas direction helps shooters track trace and bullet impact for quicker follow-up shots. It’s built with PRS-style competition shooters in mind, where staying on target under recoil matters as much as the shot itself.
