The Trinity Force crush washer can be used to secure any AR10 or AR15 muzzle break or flash suppressor. It is intended for one-time use only. Do not re-use this crush washer for multiple muzzle device installations.


For your safety, Trinity Force recommends this part be installed by a competent, qualified gunsmith/installer with an understanding of the weapon platform that the part is being installed on. Always make sure the firearm is unloaded and pointed in a safe direction when working.
