Would need a new LP, barrel, possible bolt head, recoil spring, and possible ejector. I know Ghillie has a 5.45 53 style gun.
It's a down side, but certainly not a deal breaker. I regularly clean the guns after shooting anyhow. Means nothing to me.I would say give Mike a call and ask.
Down side is most of the 5.45x39 low cost ammo is corrosive.
Just stating the obvious ... only time corrosive ammo is bad, is when you don't clean. Since started using Barrett Bore cleaner for everything, it is nearly a wash anyway ;-)It's a down side, but certainly not a deal breaker. I regularly clean the guns after shooting anyhow. Means nothing to me.
