Description
The Rugged Suppressor SA017 Shim Kit is a precision alignment tool purpose-built for .338 caliber (6.8mm) muzzle device installations. Designed to fit barrels threaded in 3/4″-24, M18x1, or M18x1.5, this kit gives you the shim thicknesses needed to dial in a perfectly concentric, square mount for your muzzle brake or flash hider.
A correctly timed muzzle device is critical to both accuracy and recoil management, and this three-piece shim kit lets you fine-tune the gap between the barrel shoulder and the base of the device. By stacking or selecting the proper shim size, you can correct minor indexing errors and lock down a secure, repeatable fit on any .338 precision rifle build.
Whether you are timing a muzzle brake or a flash hider, the SA017 shim set removes the guesswork from installation and delivers a professional-grade result every time.
