The standard AR gun is a DI gas system. Some shooters don’t like corrosive milsurplus ammo through those type of systems because it blows the dirty leftovers all over the internals.
Almost all my guns are AKs so I don’t care what kind of ammo I shoot.
People have tried multiple times to design an AR that will take 7.62x39 ammo, but most of them don’t work well for various reasons. I think most of the time the issue is the shape of the cartridge: it doesn’t work well in standard AR magazines, and the AK magazines don’t work properly in standard AR lowers.
