I had a trust made in '06, living in Oklahoma. I now want a addendum added for a suppressor and I currently reside in Texas. Do I now find suppressor, pay for it, find a Class III FFL, and somewhere during process have attorney add silencer to my trust? I've gone to BATF and so on, googled others but, I could use some "friendly forum" advice. I would like to legally make suppressors for my own use, with the proper licenses/paperwork etc. I'm not in a big hurry wanting to follow proper channels and do as much paperwork/legwork myself as possible.
