Just picked up a pretty nice yugo ak with the 1.6 mil receiver (wanted to familiarize myself with the platform) Got a great deal and it was almost lnib. The bolt, carrier, and piston are all chromed and the action cycles much nicer than any of the lower end ak's I've handled. I'm shooting brass cased yugo surplus dated 1990 something from a sealed can. I've had 5 FTE's in 400 rounds. Seems excessive for the gun that "always goes bang" I don't know crap about these things.... Any ideas would be appreciated!
