The Rugged Suppressors Shim Kit (Rugged Suppressors part no. SA001) is a set of precision shims sized for 1/2-28 threaded barrels, built to help you rotate and align a muzzle brake or flash hider so it sits straight rather than canted. Rugged Suppressors, better known for its suppressor lineup, engineers this kit to the same tight tolerances shooters rely on when timing a mount ahead of adding a can. Instead of over- or under-torquing a muzzle device to get it to index correctly, you add or remove shims until it lands square, then torque down with confidence.
