HuxWrx Safety Company 556 Shim Kit - 1/2x28

Got a muzzle device that requires "timing" for proper installation? We've got you covered. The HuxWrx Safety Company 556 Shim Kit - 1/2x28 makes it easy to achieve proper alignment in small, ultra-precise increments without any filing or frustrating guesswork. Crafted of raw, unfinished steel, each shim set ships with one Shim 1 (largest), eight Shim 2s (medium), and one Shim 3 (smallest). The large shim can be used to time out a 1/2 rotation, or it can be used as a spacer for barrels that do not have relief cuts behind the threads. Shim 2 is used in varying quantities to achieve up to 45 degrees of rotation. Finally, Shim 3 can be used when only small degrees of rotation are needed. So, what are you waiting for? Order your 556 shim kit for your AR-15-style rifle or carbine today! Compatible with 1/2x28 threaded .223 Rem/5.56x45mm NATO barrels ONLY.
