I want to SBR my HK94 and suppress it. I assume this will be TWO stamps? Se that is what keeps me from doing it, I really can't see $400 to replace my current barrel with a three lug short one and a suppressor. This is a real HK94 I have had for a very long time so I would rather be able to put it back to original one day that change it forever. The guy I once partnered with as a gunsmith is a real HK guy and will be the one I use to do the work. I give him the parts, he does the work and he has the license to also handle the paperwork. So what all do I need to do and will I need two stamps? Is a trust still the way to go or have things changed? Thanks
