Frankenmag?

[Rustship]

I have read about the so called Frankenmags for a 7.62x39 AR. I saw this yesterday at a pawn shop and picked it up. Looks like it feeds pretty well. Question, is this one of them, homebuilt, and have any of you guys seen these? First one I have seen.

Your magazine photos almost look like a AR-15 conversion for the 7.62x39mm but could be a variation of the so called "Frankenmags" . I saw some photos years ago (might have saved them) from the 4th Div Rangers website that showed what looked like a Frankenmag. The magazine had more of a curve than any US magazine that I have seen

Not homebuilt, but an older commercial mag. I don't remember the Cobblemaster's mfg. name. Haven't seen one in a while.

Just post-post ban 2004, maybe. USAmags?

ETA: "U.S.A. Magazine" is what i've managed to note on the packages photo'd on the internet. Can't find a good mfg.'s link though.

RCS found this old photo of 4th Division Rangers, and sent it along for me to post here... Note 'Franken mag' in center

Looks like mine with it in the Receiver

Tom, Could that other mag be a Sterling 40 rd?

[RCS]

Both the Sterling 30 round and 40 round magazines for the AR-180/M16 have less of a curve than the US 30 round magazine.

Agreed RCS, I had forgotten the shape.

The earliest Colt 30 round magazine have less of a curve than what is now in use. I believe they were in use in 1965. Floorplate marked .223 and have steel followers. Then came the body curve what is now in use. These first had emerald green plastic followers with the drawing number 62665A in white ink. The the stamped drawing number 62667 on the right side of the magazine body. These floorplates were marked 5.56. Hope this helps.

I disputed the authenticity of the photo on the AR15.com retro forum. I think it is a "faux" retro photo made up by some wannabees on a "tactical," where one had a 7.62x39 fake XM. Seriously, no one who depended on a weapon for their life would use a POS, cobbled together magazine like that! They also don't look like hard eyed serious players, either. Just my opinion....
