Torque Specs are too high for mounting. Stipped a hex screw which almost disabled the gun. Was able to remove the screw by drilling it out. Another issue is with the torque specs so high is once the compensator is installed it disables the ability to field strip the pistol. so you gambling on when the screw fails. DO NOT BUY.
