The Q Mini Fix 12-inch 5.56 NATO barrel assembly is a replacement barrel for the Q Mini Fix bolt-action rifle (Q part no. ACC-MINIFIX-BARREL-5.56-12IN). The 12-inch length keeps the rifle compact and quick to handle. It has a 1/2×28 muzzle thread for a suppressor or muzzle device, and a bolt-action means there is no gas system to tune. Q built the Mini Fix around short, handy barrels, and this one drops straight into the rifle.
