Found this website called DVOR. Some of the stuff they sell is close outs and it changes daily. Some stuff is cheaper by a small margin and some is a decent discount. They have AR parts and accessories on sale right now. The site is free but you have to sign up with an email to see prices. I've been looking at it for a few days but haven't bought anything yet. Anyway here's the link if anyone is interested:
