I buy a LOT of weapons from various gun forums, Chris at ADVANCED ARMS, in Pittston PA, Zip 18640 handles all my paper work at a reasonable price. He has a good selection of pistols, rifles and other related gear. A very good selection of BlackRifles(AR's) and even some BMG's. I've also bought a few used handguns from him. Customer service is A+. Also has website, just google Advanced Arms. In fact I am picking up 2 guns this week.
