CZ457 +3 Magazine Extension

This will get you the extra rounds needed for the common 12 round stages you find in NRL.  No mods needed to your existing mag, follower or spring.  Just remove you stock base plate, re-install our extension and you have 13 rounds in your mag.  

**Ordering more than one of these at a time will get you the next ones for only $7.  Please just add a note to your order how many EXTRA extensions you want and go through the check out process.  I will manually add the extras and add $7 extra for each one you order.
