Thats a wonderful rifle.
I've my 7.62x39 one. Its a honey of a shooter with brass 7.62x39 and a fun plinker with steel.
And the magazines are easily available 7.62x39 mini14 mags.
Congrats..... Those are nice! I'd love to have a 7.62x39 model. Fondled one at a gun show over a year ago (pre-covid) and almost bought it on the spot. Wish I would have snagged it. The way things are presently I probably couldn't even find one if I wanted to.
