(1 set) 308/300blk with 5/8×24 TPI
Perfect for trying to align your comp correctly like the Strike Industries Cookie Cutter on custom builds and many others.
This PWS shim kit is a replacement for  the peel washer and is used for mounting Comps.
New barrel comps normally supplied with the necessary  washers, nuts, or shims; however sometimes replacement washers are  needed if one is damaged or if installing a barrel comp 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.

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 barrel 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.
