Achieve precise alignment and optimal performance from your muzzle devices with the Dead Air Muzzle Device Shim Kit. Designed for serious shooters and suppressor users, this kit delivers the exact adjustments needed to time flash hiders, muzzle brakes, and suppressor mounts on 5.56 and 7.62 platforms without relying on crush washers that can deform or shift over time. Key Features Three precise shim thicknesses for fine-tuned rotation and indexing Clearly marked shims with notches for quick identification during installation Multiple quantities of each size to accommodate a wide range of timing requirements Compatible with 1/2-28 (5.56) and 5/8-24 (7.62) threaded barrels Simple stacking method ensures repeatable, accurate results every time How It Works Proper muzzle device timing is essential for consistent suppressor alignment, reduced point-of-impact shift, and reliable lockup. The Dead Air shim kit eliminates guesswork by providing graduated thicknesses that allow you to dial in the exact rotation needed when the device is fully torqued. Always start with the thickest shim against the barrel shoulder, then add or combine thinner shims as required. Specifications Shim thicknesses: 0.004", 0.006", and 0.060" Markings: One notch (0.004"), two notches (0.006"), no notch (0.060") Quantities: Four 0.004" shims, five 0.006" shims, one 0.060" shim Material: High-quality alloy steel for durability and precision Thread compatibility: 1/2-28 for 5.56 and 5/8-24 for 7.62 Why Choose the Dead Air Muzzle Device Shim Kit Unlike peel washers or crush washers that offer limited adjustability and can compromise concentricity, these precision shims provide clean, repeatable timing that maintains barrel-to-device alignment. This results in better suppressor performance, reduced wear, and confidence that your setup is indexed correctly every time you reinstall the device. Ideal for competitive shooters, tactical professionals, and enthusiasts who demand accuracy and reliability from their firearms accessories.
