Don't waste your time on used junk buy NOS
There are plenty of Yugos around that are in excellent, military unissued condition. Don't waste your time with used, beatup looking ones. They are cheaper but you will spend the difference in parts to repair them if you can find the right part.
I bought two of the Yugos in "excellent, military unissued" condition from J&G Sales a couple of years ago. They were $129.00 each back then. They have both been excellent rifles. I have never had any problems with them. They are fairly accurate as well. I can hold a 4" pattern at 100 yards with either of them. I suspect they will do better with better ammo.
At the time someone gave me 2000 rounds of Wolf, steel cased, hollow point ammo for them. Wolf is not known for its accuracy or reliability. I was not about to turn down free ammo though so I took it.
Unfortunately for you, the Yugos in "excellent, military unissued" condition have doubled in price in the past two years. They run about $280 now.
I still think they are worth that price. They are great guns. Very reliable and fairly accurate. Probably very accurate with good ammo.
I'm not sure who all makes the other ones but I've seen several different models at the range and folks seem to be always bitching about them not being reliable. Maybe it's the owner not taking care of the gun and cleaning it I don't know. I'm sticking with my Yugos.
The Yugos handle 300 to 400 rounds of that dirty ass Wolf ammo without jamming. That's pretty good to me.
See what others say about the other manufacturers. I would stay away from anything that appears to be beatup or damaged and I would definitely stay away from the ones that have been "Bubbafied" with the silly little worthless scope, plastic stock and bipod. That's just a waste of good money. The scopes aren't reliable because of the way they are mounted. You can't keep them zeroed.
The collector value is going up on these so putting silly assed plastic stocks, bipods and junk scopes will only ruin the collector value of the gun and make it worthless in the eyes of a collector hence driving your resale value down to less than half what you paid for the gun.
Good luck. Hope you find a good one.
