PWS - Muzzle Shim Set
This PWS shim kit is a replacement for the peel washer and is used for mounting muzzle brakes and flash suppressors. New muzzle brakes normally supplied with the necessary washers, nuts, or shims; however sometimes replacement washers are needed if one is damaged or if installing a muzzle device on a different gun.
While Peel washers require you to heat them and then peel off separate layers of the washer to get to the desire thickness, a Shim Kit is much simpler. There is no heating or peeling of layers needed. Just install the necessary combination of shims to get the precise alignment you need.
This PWS shim set is comprised of 3 different sized shims: 1 large, 8 medium, and 1 small.
