Hey hillbilly,it ain't just the upper, the lower won't accept AK mags and no one makes a 7.62x39 mag for standard lowers.
There is one company that makes a lower with interchangeable mag wells and they also make a 7.62x39 upper . CMMG makes a 7.62x39 at they call the mutant .
The big problem is the 7.62x39 cartridge is a tapered case so you need a magazine with a rather large curve in it to feed the round .
I'll look around and find out the name of the company that makes that lower with the interchangeable mag wells.
Its really the most cost effective way to go as their lower will take any at upper and for the 7.62x39 and 5.45x 39 all you need do is change the mag well and put the upper on the gun. It well also take uppers for 6.8 spc, 6.5 griendell, 5.56 , any upper that will fit a standard at lower..
When I find it I'll PMYou with the name and where you can get it.
Your Friend,
Lou
It looks like
Yankie Hill mkes a 7.62x39 upper and mags that will work in their standard lowers but the mags are expensive plus the cost of the upper .
If you are looking for a VERY accurate rifle in 7.63x39 check out the Arsenal SAM7- SF .it's a milled recivier AK imported from Bulgaria and it retails for 1.250.00 and that's what one of those ar's will cost you .
I owned one and it would hover right at 1" 3 shot 100 yard groups with Wolf ammo and the scope on it .
Here's their website. http://www.arsenalinc.com there are several models to choose from mine had a right side folding stock .
It's been said their the best ak's ever made ,give them a look. Look at the SAM7 series of rifles ,
