Constructed of 17-4 PH stainless steel, the Griffin Armament Taper Mount EZ Brake Suppressor Mount features 6 radial slots which provides effective recoil mitigation. The Taper Mount EZ brake weighs 2.0 ounces, making it one of the lightest mounts available for the Taper Mount Interface. The lighter weight reduces suppressor system weight while making the host firearm barrel lighter and more responsive to the shooter. The EZ Brake does not require timing and will interface with a 13/16" standard socket wrench for installation. The Taper Mount Thread Protector (sold separately) is compatible with this muzzle device for added protection of thread mounts.FeaturesRadial slots provide recoil mitigation with no timing requiredTaper ensures solid lock up and minimal/repeatable POI shift17-4 PH Stainless steelLustrous Black Nitride Finish
