MasterPiece Arms Cowl Induction Muzzle Brake Features The MasterPiece Arms Cowl Induction Muzzle Brake uses a multi-port blast design that redirects propellant gases outward and rearward working directly against the rifle s recoil impulse. This engineering produces a measured 63 percent reduction in felt recoil during MasterPiece Arms own testing a significant improvement that lets PRS style competitors stay on target through rapid strings of fire. Built from black nitrided high tensile strength steel the brake withstands the heat and pressure of repeated firing without degrading the finish or dulling its edges. Rated for 6.5mm caliber and smaller this brake suits the popular precision rifle cartridges commonly used in competitive shooting. A jam nut collar system lets the shooter lock the brake into the correct clocked position on the muzzle without relying on crush washers or shims to achieve proper alignment. Two machined flats on the body allow the brake to be leveled visually and also provide a surface for an adjustable wrench during installation. This design keeps the brake s internal diameter perpendicular to the barrel s shoulder which minimizes any shift in point of impact that can occur with poorly aligned brakes. Threaded 5/8x24 the MasterPiece Arms Cowl Induction Muzzle Brake is purpose-built for competitors chasing every edge in recoil management.
