Muzzle and Suppressor

The 6.5 Creedmoor Semi Auto Rifle is offered with an optional muzzle brake selection or a thread protector on its 5/8×24 threads. It is a supersonic semi-automatic rifle, so Chattahoochee Munitions recommends a flow-through suppressor rated for 6.5 Creedmoor and a 18-inch barrel. A suppressor reduces muzzle blast but leaves the supersonic crack.
