I have been asked what 7.62x39mm magazines are Colt factory 7.62x39mm magazines. I put together this quick video showing a few of the more common commercial 7.62x39mm magazines that are available with discussion of the two legitimate Colt factory 7.62x39mm magazines at the end.

I failed to state in the video that the Colt factory 7.62x39mm magazines that use the 20rd bodies will not hold more than five rounds.
