Best crush washer - JP Enterprises Double Crush Washer

I've used many standard crush washers, but this JP Crush Washer is easily the best. Much easier to time a muzzle device because you can get a lot of rotation in before it gets really tight. This crush washer looks great. Locks muzzle devices in tight but still quite easy to remove the muzzle device if needed. Bought a few more just to have some extras.
