These shim kits made by Dead Air Armament are perfect for mounting you Sandman Flash Hider or Muzzle Brake. They will also work with any 1/2 x 28 or 5/8 x2 4 threaded muzzle device you need to attach to your barrel.
This Dead Air shim set is comprised of 3 different sized shims 1 large, 8 medium, and 1 small.
- The large shim can be used to give the installer one half of a rotation or as a spacer for barrels that do not have relief cuts behind the threads.
- Shim 2 is used in varying quantities to achieve the proper alignment of your muzzle device. This shim gives the installer approximately 45 degrees of rotation.
- If needed, Shim 3 can be used where smaller degrees of rotation are needed for proper alignment.
