suppressor

Hey folks- Here's where I'm at. I'm assembling a .300 AAC home defense pistol. It's a 10.5 inch Radical Firearms upper with a stock A2 birdcage flash suppressor. What I want to do is put on a muzzle device that will reduce the report/ flash of the pistol, so it's not as loud and bright...

I'm a little confused. Do I need to fill out ATF form 1 or ATF form 4 if I plan to build my own suppressor? I'm in NC, have a NFA Trust setup, just need to fill out the right form and send in $200. Thanks

Quick question from a first time suppressor buyer... My dealer says I have to wait (going on 90 days here) for the manufacturer to transfer the unit to them before they can even start my paperwork. This is not a unique can (Silencerco - Octane 9 HD) but they had to order it as it's not...
