Rearden Mini Square Shoulder Muzzle Brake 5/8-32, Black

Proper setup starts with using an alignment rod to ensure everything is correctly aligned. Clean all relevant surfaces, then torque your muzzle device to between 15 and 25 ft-lb and apply Rocksett to lock it in place. It's critical that the muzzle device sits square to the barrel shoulder. Be aware - use on a Q can may void your warranty. Before installing the suppressor, clean the threads and taper surfaces, then torque the suppressor to 10 ft-lb. Confirm final alignment and enjoy safe, accurate performance.17-4 PH H900Compatible with Atlas and Atlas XLCompatible with Plan BThe Atlas adapter has exceeded the limit by approximately 0.05 inchesAtlas XL adapter does not experience overrunBlack nitride coating with a surface hardness of 67 HRC
