PRI Muzzle Brake Quiet Control 7.62mm 5/8″-24 Thread AR-10

The QCB has been cut from solid stainless steel bar stock for greater resistance to heat and burnout. The lead diameter is .750 and the body of the brake is .950. The 3 holes should be at 1 O’clock from the shooter when in the tightened position. Tighten the brake using a round screwdriver in the slotted hole closest to the barrel. The brake comes with a packet of shims to set your timing.
