They call it the SSR-40

Some have the folding stock welded in the folded position, some don't have the folding stock at all and are considered pistols (the same class as some of those AK pistols) and some are Class 2 SBR's with a functional folding stock. Anybody heard of these guys or had any dealings with them?
I've always wanted an MP-40 without going through the hassle and expense of trying to find and get cleared for an NFA purchase that's basically out of my reach money wise anyway. If these guys are any good then perhaps this is my chance to finally get one.
