A friend ordered a Saiga-12 early in December. It finally came in a couple of weeks ago. They were out of stock everywhere he called, at the time.
Two odd things about it:
First, it has a scope rail. That's an interesting thing to put on a shotgun...
Second, Saiga included a proof sheet in the box. The gun was proofed on Christmas Day 2008.
That makes me wonder if the supply problem is with the American importer, not with Izhmash. The gun was over two years old before it was shipped to his FFL.
