This shim kit is a replacement for the peel washer and is used for mounting muzzle devices. New muzzle brakes are 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 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.
Each shim set ships with QTY 1 of Shim 1 (largest), QTY 4 of Shim 2 (Medium), and QTY 4 of Shim 3 (smallest). The large shim can be used to give the installer one half of a rotation or as a spacer for barrels that do not have relief cuts behind the threads. Shim 2 is used in varying quantities to achieve the proper alignment of your muzzle device. This shim gives the installer approximately 45 degrees of rotation. If needed, Shim 3 can be used where smaller degrees of rotation are needed for proper alignment.

When you need the muzzle brake to be indexed correctly these are what's needed. You get 2 packs of shims in 1 order which includes 8 -.004, 8-.008 shims and 2-.054 shims. Bought an extra set just in case.

These fit perfectly on my. 308 and I was able to reuse my crush washer with the correct timing and torque value for my flash hider which is great because I needed to sight in in the next day and I didn't have a new crush washer to install. It took a little time to get the proper shim combination of shims, but it worked out perfectly to get the proper torque value set with the flash hider indexed properly. When I need more shims down the road, these will be the ones I will be getting.
