Precision Armament M11 Severe-Duty Muzzle Brake 8.6mm, 338 Caliber 5/8"-24 Thread Black

Overview

The Precision Armament M11 Severe-Duty Muzzle Brake is designed for 8.6mm and .338 caliber firearms with 5/8"-24 threads. It features a massive symmetrical blast baffle paired with two compensated front baffles to redirect gas laterally and upward, delivering over 60% recoil reduction while minimizing muzzle rise and ground disturbance. Computer-optimized via finite element analysis for an optimal strength-to-weight ratio, it is precision CNC-machined from high-strength HTSR 400-series stainless steel bar stock. The design utilizes high-tolerance Class-3+ threads machined in the same operation as the bore aperture to ensure perfect concentricity, reducing bullet flight yaw and improving accuracy. A closed bottom reduces dust signatures during prone shooting, and top/bottom wrench flats facilitate installation.
