The AR-15 1/2 Crush Washer is an essential component for ensuring your newly assembled AR-15 is perfect. This simple piece of stainless steel slips onto the end of your threaded AR-15 barrel and allows the flash suppressor to be torqued down to the specified level of pressure.
The crush washer acts as a base layer to ensure that during the torquing process, no damage is done to the shoulder of the threaded portion of your AR-15 barrel. This will ensure that the threaded portion is in perfect condition to allow the muzzle device to be changed out.
