CMMG has recently announced they have discovered a defect in their CMMG 5.7 AR Conversion Mags.
CMMG states “The defect can sporadically allow cartridges to become unseated from the feed lips causing them to eject out the top of the magazine.
CMMG has redesigned the CMMG 5.7 AR Conversion Magazine to ensure cartridges remain fully seated in the feed lips.
CMMG will be offering free returns and replacements to all consumers who currently own a CMMG 5.7 AR Conversion Magazine.”
