Yes, Silencer Shop and Silencer Central. Silencer Central is the one that ships directly to you. They are a direct to customer vendor. Silencer Shop is a distributor that allows customers to pay them directly, but the actual transaction (paperwork) goes through a local dealer that is in their network.
Dave, you are also confused. The two places are nowhere near equal. Silencer Shop has the largest inventory in the country and, in my opinion, has helped significantly to make suppressors mainstream. Their kiosks, simple trusts, and extremely large dealer network have made it possible for people to get through the process easily and much quicker than if we were still using our local FFLs to handle everything.
I get that you don't like SC and are POed that it took a bit longer to get your suppressor than you thought it should, but take it from someone who has been in the game for a long time. It is never going to be a quick process. If you want to play the NFA game, you have to be patient.
