This adhesive shim is designed to help S&W 15-22 magazines fit more securely in an AR15 mag well by taking up slack and supporting proper function with the Catch22 system. It is also described as a way to use 15-22 magazines in a Kriss Defiance DMK22 that already has a bolt catch, rather than relying on the factory Kriss magazines. The adapter is intended for shooters who want a simple, magazine-by-magazine setup, since one is needed per magazine. At this price point, it is a straightforward compatibility accessory rather than a standalone upgrade with broader features.
