I have one I'd consider parting with. It's a 12ga, 20" iac norinco. It already has the 2 drop mod and is slick as frozen snot. I have no clue who worked it. Runs pretty good if I load and lever it correctly. Pm me if you're interested.
my grandfather used to tell me the whole story about Damascus guns not being safe with smokeless loads was a marketing ploy just to get people to buy new shotguns. he always shot factory smokeless loads out of his old 1800's Remington. (which was the first gun I ever fired) I hated that monstrosity... it was abusive and scared the hell out of me (I was 9 or 10). I stuck with my bb rifle...
I wish I knew what happened to it.
