The Saigas imported here in that time period were in a "Sporter" configuration to get around one of the bans. The one in the OP's link looks like someone did some of the grip conversion, but didnt want to get into changing out the handguard and left it alone.
They are basically Russian AK's converted there for import here, and then people here, converted them back, at varying levels. Some got them pretty close to what they were, some did it piecemeal.
This was my Mark Krebs "restored" Saiga AK103K in 7.62x39. It was one of his early conversions done for the defunct Kalashnikov USA out of Fla. back in the early 2000's and before he was putting his name on them. I actually had a second gun on order after getting the first, but the company went tits up before I got it.
The Russians make good guns. They may not have the fit and finish Amercians seem to expect, but they are well made, functional, and accurate.
They dont have a target type iron sight set up like the AR's, but an AR and AK fitted with a red dot, and shot a little more realistically, will shoot very much the same.
Even with the original factory type irons, they will shoot well if you can.
