S&W Stick-On Magazine Adapter

The S&W 15-22 magazine will work great with the Catch22 to provide true last-round-hold-open functionality. The only issue with the 15-22 magazines is that they are shorter (front and back length) than a standard AR magazine.


To fix this, AR Catch22 magazine adapters can stick right onto your 15-22 magazines for a quick and easy way to shim the magazine and solve this issue. 


One adapter is needed per magazine.
