Classic Arms Inc. lists the Saiga .223 and 7.62x39 for $249.95 and the .308 at $349.95.
Most people think of shotguns when you mention Saiga, but the rifle I bought sure changed my way of thinking.
The rifles come with a standard AK scope / accessory mount on the left side of the receiver, although it seems better made and a bit tighter than the military style AK's. It does retain the direct gas piston system and the same safety lever. Handling is remarkable - when you first look at it, it seems unbalanced - with rapid sight acquisition and minimal recoil.
