Achieve proper alignment without dealing with a peel washer.
This PWS shim kit is a replacement for the peel washer, and is used for mounting muzzle brakes and flash suppressors. While peel washers require you to heat them, and then peel off separate layers of the washer to get to the desired 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.
Shim 1 (1 Each): This can give the installer 1/2 of a rotation, or be used as a spacer for barrels that do not have relief cuts behind the threads.
Shim 2 (8 Each): This shim can be used in varying quantities to achieve proper alignment. This shim gives you approximately 45 degrees of rotation.
Shim 3 (1 Each): If needed, this shim can be used where smaller degrees of proper rotation are needed.
