The guy that got the Tromix suppressed Siaga is on Silencertalk. If you do a Google image search for "suppressed shotgun" it comes up in one of the thumb nails, but the image itself has been taken down.

This stuff is honestly a pipe dream for me. I just don't currently have the funds available to get what I want, so I tend to try and not talk about it too much lest I become that guy who always talks about what he's going to get, but never does it. There are a bunch of people on here who have NFA stuff, but for some reason, they hardly ever talk about it. NFA stuff still seems kind of taboo on this site to me. I don't really understand why though.
