CZ457 Magazine Extension
I bought two of these extensions for my CZ457 magazines. I assembled them and went to the range. When I got there I could only load 10 rounds in each magazine. I called AO and asked about this problem and found that it usually is become the user installed it wrong. Thy sent me two Youtube links how to do it correctly (also already on their website). I followed the video and BOOM! Now they both work correctly. My fault... They work exactly as advertised. Thank You AO Customer Service for helping me, and making me not completely feel like an idiot!

Works, butt…
This is my 4th extension and just like the others it needed attention.
The factory follower and “catch” on the extension, preventing space for extra rounds. A little “fitting” has these running 100% -
457 +3 extension
Pretty much a mandatory add on for NRL22. Does not affect feeding and easy to install, just be careful about the magazine floor plate retaining pin.
