Overview

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.

Considerations & Trade-offs

  • One adapter is needed per magazine, which adds a small extra step and cost if you want to equip multiple magazines.
  • The product is an adhesive shim, so it depends on proper placement and adhesion rather than a mechanical attachment.
  • Its purpose is specific: it addresses mag-well slack and bolt-hold-open function, not broader magazine or rifle compatibility issues.
