Wilson Combat Shim Kit Mount 5/8X24

The Wilson Combat Shim Kit Mount 5/8X24 is a precision mounting accessory built to dial in the fit between your suppressor and muzzle threads. If you're running Wilson Combat's Rapid Thread or Flat Back suppressors on a rifle threaded 5/8" x 24, this shim kit gives you the adjustability needed for a tight, rattle-free connection that stays put under fire. Suppressors and their host rifles live in a world of tight tolerances—even a fraction of a millimeter of play can affect where your rounds go and how much signature you're really cutting. These precision-ground shims solve that problem without fuss.

Installation is straightforward: swap out worn or incorrect shims with the right thickness from this kit, and you're done. No gunsmithing, no special tools. The shims are ground to exacting specs, so you get a consistent, repeatable fit every time you mount your can. This is especially valuable if you're running multiple rifles with the same suppressor, or if you need to match thread pitch across different hosts.

Note that this kit is engineered specifically for the 5/8" x 24 thread pitch and is compatible with Wilson Combat Rapid Thread and Flat Back suppressor interfaces. It is not designed for .458 SOCOM or HAM'R rapid thread platforms, so verify your muzzle threads before ordering.

Frequently Asked Questions

Will this shim kit work with my Wilson Combat suppressor?

This kit is compatible with Wilson Combat Rapid Thread and Flat Back suppressors that use 5/8" x 24 threads. If you're running either of those interfaces, you're good to go. If your suppressor uses .458 SOCOM or HAM'R rapid thread, this kit will not fit.

What's the 5/8X24 thread pitch, and how do I know if my barrel has it?

5/8" x 24 is a common muzzle thread pitch for centerfire rifle barrels, especially .30 caliber rifles. Your rifle's manual or spec sheet will list the thread pitch. Many modern rifles are threaded this way, but always verify before purchasing mounting accessories.

Do I need tools to install these shims?

No. Installation is fast and straightforward—simply remove the old or incorrect shim from your suppressor mount interface and replace it with the right one from this kit. No gunsmithing or special equipment required.

Why would I need shim kits for my suppressor?

Shims take up small gaps between your suppressor's threads and your barrel's threads, eliminating play and rattle. This improves the consistency of your shot and can affect point of impact. If you're moving a suppressor between different rifles or want a tighter fit on a particular host, having the right shims on hand makes the adjustment quick and repeatable.
