Guys, there's a fairly local leathersmith who makes some very good holsters that I'm going to talk to about making up some of these Afghan mag carriers.
I'm going to see how much he'd charge, and have him do them for both AK-47 and AK-74 magazines.
I'd also reverse the way the mags are carried, I think it would make it much easier to get them out of the pouch that way.
