Muzzle Device Shim Kit

The Dead Air Armament Muzzle Device Shim Kit is available now from LM Ironwerks, a licensed FFL/SOT dealer in Louisville, Kentucky.

The Dead Air Shim Kit for barrels with 1/2-28, 5/8-24, 3/4 or M18 threads is composed of three different shim thicknesses. The graphic on the packaging details the thicknesses and identifying features of the shims included with the kit. Always place the thickest shim(s) on the barrel first.

What It Does

This is a replacement or accessory part that keeps your suppressor or mount working the way it should. Small parts like collars, shims, seals and covers wear out or get lost over time, and having the correct part keeps everything aligned, secure and running reliably.

Before You Order

Parts like this are model specific. Check that it lists your suppressor, mount or host before ordering, and follow the manufacturer’s instructions when installing it.
