The WASR started life as a 10rnd locap mag well gun, which explains the minor difference in the receivers of WASR and SAR. General terms here: A tight mag fit can be made looser, loose is fast and reliable in battle, floppy is a reliability hazard. Genuine matter of degrees here, and some mags are a wee bit fatter than others. A known good AK reference feel is nice. 5 US parts should have also been added, usually pistol grip, gas piston, chintzy fcg. Besides normal Romy variations in fit/finish that are just personal preference, make sure the sights are straight, no real gas block cant, and the side rail is parallel to the receiver/bbl. Romy AKs are much better than the 1999 into here, but bad examples still slip thru. Hicap WASR or SAR wholesale at about $280, add shipping/ffl stuff, plus your value assigned to hand picking a non-lemon.
