The original Catch22 Bolt Catch. Use with S&W or Kriss magazines for best functionality!
Uuse the stock-on adapters to shim each magazine and make them fit properly in a standard AR15 magazine well (one needed per magazine)
Use the clip-on adapter to shim the magazine well instead of the magazines (one needed per lower)
Some magazines have a light spring which doesn't always engage the bolt catch well (ex: KRISS Defiance). Use this replacement spring to help
your bolt catch function well with all magazines.
Sorry, we can't ship this outside of the USA!
