It is a Saiga .223...
You can get a Saiga 7.62*39 for $349 delivered...
Don't buy from Arsenal in Nevada and it will not cost you $800+
I assume you converted it (which, of course, would add to the cost) - but if you purchased it as pictured, you got a heck of a deal!
I can definitely recommend the .223 Saigas, either way. I've built several 7.62 AKs from parts kits, and I definitely prefer converting Saigas. Nothing beats a Russian bolt/bolt carrier, in a Russian receiver, with a Russian barrel, etc., etc., etc...
