The Dead Air Silencers Muzzle Device Shim Kit DA001 is composed of three different shim thicknesses for the most precise timing of your muzzle device. The 1/2″-28 thread pattern kit includes shim thicknesses of .004″, .006″, and .060″, with a matte black finish. The kit contains four .004″ thick shims (40 degree rotation, 1/9 turn), five .006″ thick shims (60 degree rotation, 1/6 turn), and one .060″ thick shim (1.7 turns).
The graphic on the packaging details the thicknesses and identifying features of the shims included with the kit. Always place the thickest shim(s) on the barrel first when performing installation. These thin stacked washers give you precise clocking for mounting muzzle devices like Dead Air Keymo and Xeno, built lightweight yet strong to handle torque without altering alignment. Whether fine-tuning suppressor fitment on AR-15s or other 1/2″-28 threaded barrels, the DA001 provides the precision shims needed for optimal muzzle device alignment and reliable performance.
