One of the benefits of Surefire’s muzzle devices is the highly intuitive timing system, which uses several color-coded shims to achieve your ideal positioning. But, as with any small parts, it’s very possible for these to disappear. If you’re moving your Surefire devices between rifles and need a new shim kit, Sure Fire have got you covered. This shim kit has everything you need for mounting a 5.56 surefire device on 1/2×28 threading.
