Convert a regular Magpul PMAG M3 into CMMG's innovative 30 round 9mm magazine for AR-15 platforms with the CMMG drop in kit.
Featuring a clever insert and spring system which fits inside a standard Magpul PMAG, offering advantages of the classic hardwearing Magpul design, sizing and grip features with a reliable 9mm feed.
