Will this upper work with a mil-spec ar lower or do they require a special lower? I have an extra lower, Stag, that I would be willing to keep and put this upper on it. Is the mag well and mag a different size for the 7.62 upper?

Wasn't aware that Colt made any 7.62 uppers.

If they did they were the 7.62x39 not the 7.62x51 (.308) nor the 7.62x54R the other russian round.

the Combloc 7.62x39 is shorter than the .308 7.62x51 and therefore might fit into a standard AR mag.

the Mini14 mag is about the same size as the mini30 isnt it ?

Even if it fits I don't believe you could fit more than 5 in it and feed reliably. The 7.62X39 has a lot more taper than the .233 (hence the banana look of the AK-47 mag compared to the AR.)

I have a DPMS 7.62x39 upper on a Stag lower and it shoots great....I'm just having some mag issues.

Colt sold 7.62x39 conversion kits and rifles back in the 1990's. Here are some pages from the Colt catalog and conversion kit user's manual. I believe they used AR-15 mags with a different follower to accommodate the 7.62x39 cartridge. I believe the magazine floorplate was also marked 7.62x39.

Actual colt parts might be hard to find but AK mags could be used with the lower that SFVDealer sells and then use a colt barreled upper.

I knew Ive seen colt 7.62x39 mags at the Gun Shows in the past I knew a guy that did reno shows and he had alot of these mags.

I have a colt lightweight sporter in 7.62x39 that I bought new in 1994 or 1995.

It uses a colt mag that is exactly the same as a colt .223 mag, but has a tapered block inside that allowed only 5 rounds. Whomever posted that the taper of the bullet precludes reliable feeding over 8 rounds is correct.

USA made 30 round mags that worked perfectly. They were not modified AK mags, but were banana shaped mags they manufactured. Much longer than an AK mag for the same 30 rounds.

When the fed ban came down, USA MAGS tried to jam out a ton of their "Frankenmags" using AK bodies welded to their own tower, and these units are CR@P!

I was fortunate enough to buy 5 real top notch USA 30 rounders before the ban. Trust me at age 20, 5- $50 each mags and a $1400 rifle were hard to afford. I bought 1 USA "Frankenmag" and would stomp it flat if I didn't hope to "repair" it someday when I find another "real" USA body.

As for the Ak mag lower, I think some mods might be needed on the bolt for reliable operation. Figuring that true Colt 7.62x39 parts are worth their weight in silver (At least), I would use a Model 1 Sales or DPMS for this project.
