BigBill...
My Rumanian gun has the following markings on it, "C. A. I. ST. Alb, VT". It also says "SAR 1", this rifle will take the 30 round magazine. I see what you mean on the fit and finish, there is a gap on the rear stock to the receiver, the gas piston housing was put on a little canted.
The rifle originally came with the black plastic pistol grip, and it did not last long as the mounting screw broke through it after tighting up as it kept shaking loose. I put a new Chinese type military grip on it, it is much stronger and has not acted up over the last 3 years.
Stan in SC...from what I have read Russian steel is supposed to be very good. It could be that the guy who heat treated it may have had a hang over, or maybe it is supposed to wear in abit, not sure. I agree with you on your observations on the Russian hammers, and will keep my eye on the next one I buy and see how it holds up after a year at the range as I have been thinking of getting one of those Russian made VEPR AK-47's.
Thanks.
