Right, so after researching this one stupid, I think this is what its going to come down to. I'm going to have to just go ahead and buy the two things, and see what I can come up with.
Thanks for your guidance folks.
I took a look at what info I could find on the AI shell, and I don't think its going to be what I need, but I'll keep my eye on it.
EDIT: Wait. On the Real Deal AK-74, the tubular structure under the barrel. Isn't that just a cleaning rod, which means I could probably just dremel it off the CYMA to simplify the mount?
EDIT: Oh, look. On my wifes, you don't even have to dremel it. Problem 1 solved.
EDIT: Anyone got a bunch of AK spare parts lying around? I'm looking to add a receiver mounted sling swivel, like the one on this rifle. Any thoughts on the best way to do that?
