I am far from an expert on suppressors. However, AAC, here in Georgia, is a major manufacturer of them. The Trading Place Pawn and Gun Range, here in Monroe, is an AAC stocking dealer. You can call the shop @ (770) 266-0281. Ask for Justin or the owner, Blake Knight. They can provide all the information you would ever want to have on suppressors. They can even set up the trust to get the tax stamp for suppressors and short barrel rifles.
you will need to get in contact with a class 3 FFL. They should be able to walk you through the process of getting a suppressor. Good information on ar15.com on the process also. Ohio just passed legalized hunting with suppressors this year.
