Rearden Manufacturing Mini Muzzle Brake, .45 Cal 1/2-28

The Rearden Manufacturing Mini Muzzle Brake (brand part no. 10065) is a compact .45-caliber brake threaded 1/2-28, built with a square-shoulder design that indexes cleanly against the muzzle for consistent, repeatable installation. Rearden Manufacturing designed it to cut recoil and muzzle rise on .45-caliber pistol-caliber carbines and similar builds without adding significant length or weight to the muzzle end.
