The Wilson Combat Shim Kit (Wilson Combat part no. SP-RTMB-SHIMKIT) is a set of precision shims sized for 5/8-24 threaded barrels, built to help you rotate and align a muzzle brake or flash hider so it sits straight rather than canted. Wilson Combat builds this kit to the same tight tolerances the company is known for on its match-grade rifles and pistols. 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.
