Deadair Da004 Muzzle Device Shim Kit M18$10.00
Availability: In Stock
The Dead Air Armament DA003 Muzzle Device Shim Kit is a precision accessory for shooters running suppressed setups on 3/4-inch barreled firearms. Threading tolerances vary across rifle barrels, and a shim kit lets you dial in the perfect fit between your suppressor and muzzle device—eliminating gaps, rattle, and potential alignment issues that affect both performance and shooter confidence. This kit gives you the flexibility to match your specific barrel, whether you're building a precision rifle, tactical carbine, or hunting setup.
The kit includes three different shim thicknesses, each engineered to stack and layer for fine-tuned spacing. Dead Air's packaging graphics clearly identify each shim and its thickness, so you'll know exactly what you're working with during installation. The general rule: start with the thickest shim closest to the barrel, then work forward with progressively thinner shims. This layering approach lets you achieve a tight, rattle-free union between barrel threads and your suppressor interface.
Shimming is a straightforward process for anyone comfortable with basic suppressor mounting, but it's especially valuable if you're running multiple suppressors across different rifles or if your barrel's thread pitch sits at the tighter end of the tolerance band. A properly shimmed setup not only feels more solid—it ensures consistent suppressor alignment for every shot.

| Model | DA003 |
| Application | 3/4-inch muzzle devices and suppressors |
| Contents | Three shim thicknesses |
The DA003 is designed for 3/4-inch threaded barrels. If your barrel uses 1/2-28 or 5/8-24 threads, you'll need a different shim kit.
Place the thickest shim directly on the barrel threads first, then layer progressively thinner shims in front as needed to achieve a snug fit with your suppressor. The package graphics show each shim's thickness and identifying features to guide your selection.
Yes. The shims are reusable components. You can stack different combinations across multiple suppressors and muzzle devices, depending on your thread fit tolerance.
Not always—only if your suppressor or muzzle device threads sit loosely on your barrel or if you want to eliminate rattle and ensure perfect bore alignment. Many shooters find shimming worthwhile for consistency and peace of mind.
