Precision shims allow you to achieve correct port alignment and optimal gas redirection without overtorquing or under-torquing the device. This kit is specifically designed for Wilson Combat's RT (Rapid Thread) muzzle brakes with 1\/2x28 threading, commonly found on AR-15 platforms chambered in .223\/5.56.\u003c\/p\u003e\u003cp\u003eEach shim is precision-machined to maintain concentricity and barrel harmonics. Installation is straightforward: stack shims as needed behind the muzzle device until proper timing is achieved, then torque to manufacturer specifications.
