WILSON SHIM KIT RT MB WHISPER 1/2X28

Description

Getting a suppressor or other muzzle device to index correctly on a threaded barrel is rarely as straightforward as it looks. The threads themselves may be cut true, but the device still needs to rotate to a specific clocking position — and without some way to take up the gap, you are left choosing between a loose mount and a device that stops short of where it belongs. Wilson Combat’s shim kit for the Rapid Thread and Flat Back attachment system solves that problem directly: a selection of shims lets you fine-tune rotational indexing so the device seats flush and locked at exactly the right orientation, without forcing the barrel or rocking the mount.

The kit is built around the 1/2×28 thread pitch, which is the standard on a wide range of centerfire pistol and rifle barrels in common chamberings. If you already run Wilson Combat’s Rapid Thread muzzle attachments, this shim kit is the purpose-built complement to that system rather than a generic aftermarket workaround. Having the correct shim thickness on hand before installation saves you the frustration of a device that indexes poorly and has to come back off — a small investment that pays off the moment you are fitting a new can or compensator for the first time.

At roughly the cost of a box of ammunition, it is an easy addition to any Wilson Combat Rapid Thread setup and the kind of component that tends to sit in the kit bag until the exact moment it is needed.
