This. Sold off all of my x39 and after I sold my SE and SKS. I swore I'd stick with 556 from now on and then these come out. Guess I have to re-stock.
I missed the boat on cheap 223 ammo. With crates of 7.62x39 still available for like $0.28 per round, I can't reload rifle ammo for that cheap (primer, powder, bullet). So I'm totally on the x39 bandwagon. SKS, Type 81, MRA (bolt), Ruger (bolt), Norinco (bolt).... probably need a CZ at some point to go through the 100,000,000 rounds of ammo I have
