Think the EE would be the closest you'll get here. Or just buy a second sks. That's what I did. Cheapest semi centre fire there is. Get a deal with a case of ammo and be happy you got it when it was still cheap.
Hahahahahha.... Every forum branch here suggests buying a second rifle for parts or just to have as a backup/secondary. At this rate I'll need a second gun locker and gunsmithing lessons before the years out!
They do breed quickly!
