SureFire Muzzle Device Replacement Shim Kit – 1/2×28


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, we’ve got you covered. This shim kit has everything you need for mounting a 5.56 surefire device on 1/2×28 threading.

  • Matches 1/2x28TPI thread pitch
  • Includes 12 Shims of Various Thicknesses

    Needed to replace the shims for my CTN Comp, needless to say, these worked as intended. Got to me quickly and have made me a frequent customer of this company.
