I think some link a RRA dedicated 7.62x39 lower that has a magwell designed to accept and feed the round. Looks reayll interesting.

I had a x39 AR that I eventually got to work. I had an ejection problem then a hammer that was to light. Once those two things were remedied it was a joy to shoot. The only problem was at the time the local ranges didn't allow bi-metal ammunition. I can shoot .300BLK brass cased for less than x39 brass cased.
I tried going with a 7.62 X 39 cartridge for one of my rifles. The magazines were always double-feeding so I canned that idea. From now on I only use an AK type rifle for my 7.62 X 39 shooting needs. About the only other idea to go with for this shooting goal would be an AR-47 rifle. Those rifles use AK magazines set up in an AR lower. The AR-47s were popular with the SEALs for awhile.
