Advanced Technology AR-15 Crush Washer 5-Pack 223/5.56 Black Oxide

The ATI Outdoors AR-15 Crush Washer 5-Pack is a set of five black oxide steel crush washers for AR-15 pattern rifles. Crush washers are used between a muzzle device and the barrel shoulder to set alignment and to take up the thread tolerance when a flash hider, compensator or muzzle brake is installed.

This pack is sized to fit AR-15 barrels threaded 1/2-28, the standard thread pitch for 5.56x45mm NATO and .223 Remington barrels. The steel construction is finished in black oxide, which matches the black finish common on AR-15 muzzle hardware.

Each pack contains five washers, so spares are on hand when a washer is deformed during installation and needs to be replaced.
