The Rugged Suppressors 5/8-24 Shim Kit (brand part no. SA002) gives suppressor and muzzle-device owners a simple way to correct thread indexing on a 5/8-24 tpi mount. When a suppressor or muzzle brake threads on tight but lands slightly off from true vertical, a thin shim inserted between the threads rotates the final resting position without loosening the fit. Gunsmiths and home builders keep a set of these on hand because thread depth varies slightly from barrel to barrel, and a shim kit is the fastest fix that doesn’t require cutting or re-threading anything. It’s a small, inexpensive part that solves an annoyingly common fitment problem.
