RN,
I have a factory converted Saiga in 7.62x39 (Arsenal SGL-21). The quality is absolutely top shelf, but Saiga's have some non standard parts. The bolt and gas piston readily come to mind.

My 5.56x45 Arsenal SLR106 is a better choice (owning to the rock solid folding stock and caliber - I prefer the power and legendary relibality of the 30 cal but the weight and non-NATO issues make it my second choice). I also like the standardized internals. Outside of being a 223 bolt with a spring loaded firing pin - everything looks normal AK.
