Dead Air Shim Kit M18, Black

The Dead Air Muzzle Device Shim Kit from Dead Air Armament is a precision solution for firearms with 1/2-28 or 5/8-24 threaded barrels, delivering three distinct shim thicknesses to fine-tune muzzle device timing and alignment. Designed to support accurate installation and optimal performance, the kit helps shooters achieve a clean barrel suppression fit by enabling precise shimming with a clear guide that identifies each shims thickness and features. When assembling a muzzle device, start with the thickest shim(s) on the barrel to establish a solid baseline, then layer in progressively thinner shims to dial in perfect alignment and tuning for voice-perfect timing and reduced point-of-impact shift. This straightforward shim system supports quick field adjustments and reliable, repeatable results across a range of handgun muzzle devices, making it a valuable addition to any gunsmithing or maintenance routine. The compact, durable kit integrates seamlessly with existing handguard setups and can simplify on-site tuning, ensuring shooters can maximize performance and accuracy without compromising reliability.
