I have owned many Romainia AK's and SAR's and WASR GP's are typically the higest quality.
My first SAR2 was a beautiful gun with excellent fit/finish,except for the canted front sight. It was unsightly, but it shot perfectly straight. I had a few WASR10's, 2 of which were completely non-functional, but fit/finish was okay. Typically, they are reliable, decently accurate but shoddily produced weapons. My experience seems to indicate that the original SAR's are the best(seems like the later ones had more problems) and the new WASRGP is a close second, if not as good.
The new WASR's like the dimples on the receiver to secure the magazine and restrict lateral movement. This has never contributed to any malfunctions in any of my guns and has never caused anything more than a rattle. I would try to locate an original SAR1 or buy a brand new fixed stock WASR GP. Both are excellent choices and the GP is very close to a military AKM.
