These brakes are expertly designed for PRS (Precision Rifle series) competitions, where extreme recoil reduction is essential for keeping the shooter on target during rapid follow-up shots. Through our specialized testing system, we have refined the design to achieve a remarkable 63% reduction in recoil, enhancing overall shooting stability. The innovative jam nut collar system allows shooters to securely position the nut and brake against each other at the optimal point on the rifle's muzzle. Featuring two machined flats, this design enables easy leveling of the brake body and provides a secure interface with an adjustable wrench for hassle-free installation. By eliminating the need for ground shims, this system also ensures that the inner diameter of the brake aligns perfectly perpendicular to the barrel's shoulder, significantly minimizing any initial point of iMasterPiece Armsct shift. Elevate your shooting performance with this advanced brake, designed for precision and control in high-stakes competitions.
