The Rugged Suppressor Shim Kit SA017 is a precision alignment solution for .338 caliber suppressors and muzzle devices. If you're running a suppressor on a .338 rifle and want rock-solid concentricity—or need to dial in a muzzle brake or flash hider—shims are essential. This kit handles three of the most common .338 barrel thread patterns: 3/4x24, M18x1, and M18.5x1. Whether you're building a precision rifle, swapping suppressors between uppers, or just ensuring your muzzle device sits true, having the right shim kit on hand keeps you from guessing or gambling with concentricity.
Rugged Suppressor's shim kits are purpose-built for alignment, not an afterthought. The .760" inner diameter and .875" outer diameter of these shims are engineered to work with Rugged suppressors and other quality muzzle devices designed for these thread patterns. Since suppressor performance and longevity depend on proper centering, using the correct shims—rather than stacking random washers—gives you confidence that your setup is right.
This is a consumable accessory that serious shooters and gunsmiths keep in stock. Whether you're a long-range hunter, precision rifle competitor, or someone building multiple .338 setups, the SA017 kit covers the thread patterns you're most likely to encounter.
