I have been thinking about getting a can but have no knowledge on them. Can I submit my Form 4 now and pay the 200 dollars even if I don't buy a suppressor until later down the road?
I was in the same boat as you. Go to www.Silencershop.com
they have a very comprehensive website that will answer almost all of your questions. Also go back a couple of pages in this section, there were a couple of good threads about 10 days ago. It's much simplier than people think, you just need to follow the steps.
I used the 199Trust.com for my trust and it was incredibly quick and easy.
