Overview
This Rugged shim set is comprised of 3 different sized shims 1 large, 8 medium, and 1 small.
- 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.

Classic shim set. Works great as it was intended.

Good shims, only complaint is that the timing for mine did not align to what I expected, they include a 1 (large), 3 (medium), and 2 (small), however I could just barely get the 12/6 timing right with using all of them except 1 small.
