I have been watching 1016 and 5112 and a big thanks to Randb on those and any others that have worked on them. What I am asking is a question about pinned suppressors or integral suppressor. I have two rifles specifically that I am I was looking at possibly getting them for a PS90 and a GSG5. Both I would like permanent suppressors so as not to overall lengthen the rifled. I was told by a local class 3 dealer in the Tacoma area that if I buy a suppressor I could send the barrel off to Gemtech and they would cut the barrel and "pin" (don't know if that is the right wording or not) them together so as to avoid SBR of the rifle. However, looking at gemtech website they state to cut the barrel I have to have a SBR tax stamp for the rifle. Is this true? Or is there a new ruling that the local dealer isn't aware of? Also another told me that I could buy a shortened barrel and have it directly shipped to a gunsmith have them pin the suppressor to the barrel. The other thing I was looking at is possibly just going with an integeral barrel from SRT I see that they can build one. Is it worth while and easier to go this route and actually legal? Or is the pinning the suppressor somewhat of a grey area? It seems that I am getting different information from different dealers and would like to know what is actually legal.
