Great crush washer for AR 10s
While AR 10 rifles are not as popular as AR 15s, everyone still looks to make the gun look more menacing by changing the muzzle brake or suppressor. Many muzzle brakes or suppressors don’t come with crush washers and many times the old washer can not be used again because you can’t time the device. Always good idea to have extras on hand.
