Beware of larger-diameter cartridges with the AR-15. Since the external dimensions of the bolt stay the same, the rim at the bolt face must be thinner to accommodate the larger-diameter case of the 7.62x39, which causes this:
I would expect this not to be an issue with AR-10 type rifles, which were designed from the ground up for the 7.62x51 NATO. I don't know what availability is like for AR-10s in that caliber, but I would assume it would be hard to find because AR-10s in general are much less common than AR-15s.
ALSO, I have read about issues with:
1) magazine performance due to the straight AR mag wells. Look at how curved a normal AK mag is, which is a function of the cartridge shape; an AR mag (and the mag well it goes in) is much straighter. This would affect AR-15s as well as AR-10s.
2) feed ramp needing modification to feed 7.62x39 reliably.
I don't own an AR, because I prefer AK-style rifles. They are cheaper (both rifle and ammo), more reliable, and were designed from the ground up to fire the 7.62x39 (which I prefer to 5.56×45mm NATO). While ARs edge out AKs in precise target shooting, for all practical defense applications under 150 yards, the AK is the better choice, IMO.

The one thing that always bugs me about AKs is the horrible sights. If you do get an AK, look for one that has rails (or one where they're easy to add, for example by swapping with grips that have them built in, etc) so you can add a red dot etc. I dunno why iron sights are always so bad on AK-style rifles...?
