Saiga 308? What am I looking for and where do I look? I dont' want to spend an arm and a leg. I want something strictly for self defense, 16" bbl that I could put into a Kushnapup stock if I like the way my current Saiga 12/Kush turns out. Even if I don't like the Kush, I still want a S308 for home defense, but what do I need to look for? I see prices from 600 to infinity?
