Crush Washer for 300 BLK

Crush Washer for 300 BLK

  • 457


This is like a standard AR-15/M16 crush washer for use with end-of-barrel attachments such as flash hiders, muzzle brakes, and thread protectors. The main difference that makes this special is the outside diameter is only 0.75" which means it fits well on 300 BLK barrels. They are super thin so don't go all He-Man when tightening your muzzle device.
