Russia is firmly wedded to the 5.45x39.
The only recent combat use of the 7.62x39 was by Spetznaz in house-to-house fighting in Chechnya, and only because the 7.62 punched through walls better.
Here's the Ohio Rapid Fire I bought last Fall.
It's a new, all matching Bulgarian de-milled kit on an Arsenal/Global fully hardened receiver.
I refinished the wood, and replaced the stock with an Ironwood Designs butt.
Absolutely top quality workmanship, accuracy, and reliability.
In addition, you get some nice accessories with the ORF rifles.
The rifle ships in a plastic gun case, and comes with a new Bulgarian orange bayonet, sling, cleaning kit, 4 strippers and a stripper guide, a new/like new black Bulgarian magazine, a black US made pistol grip, a stainless gas piston, a black poly buffer, and a Tapco G2 trigger unit.
