O.K., so I want to put a 7.62x39 upper on my M&P 15 lower.  This may be a stupid question, but can I load that cartridge in a standard 5.56/.223 mag?  If not, what kind of 7.62x39 mag will work or where can I find an adapter?  Help an idiot out, please.


I understand that standard AK mags are the ones to use, I'm not sure that it works with the 5.56 lower.

            You'll have to get new mags for 7.62x39 and that's one problem there are scarce and mostly 5 or 10 rounders.
  Try CProducts they have developed a 30 round mag but I've heard they have problems.

AK mags will not fit your AR.
