Be careful using any muzzle device... For accuracy, I won't torque any higher than 15 foot pounds. The torque will actually compress the barrel that can be measured with a muzzle erosion gauge..The higher the torque, the higher the compression..This is why barrels that require a high torque setting with a suppressor will have un-even bore wear at the muzzle and will be less accurate over time when the suppressor is removed..
