This brake has an integral lock nut with a left hand thread to allow easy and accurate clocking for the brake.  The 2 Port Brake will provide moderate recoil reduction when used without a suppressor and provides a very sturdy mount for the 338LM suppressor using both the conical section in the rear as well as the parallel section in the front for maximum concentricity.
