Hi, I am new here, and what Imchur said is 100% dead on. I just got a Armalite Stripped lower, and Quality is Great. I found some great deals on Gunbroker, GunsAmerica, Auction Arms. You have to be quick, because stuff goes fast. I got my receiver on GunsAmerica, and it was sold, but the Buyer backed out, and I got a great deal. Would it be cheaper to buy a complete gun? Yes, maybe, but you will get alot of satisfaction after you pull the trigger, of the the one you built. Just be careful and ask questions, these guys on this Forum have the Answers, they have helped me. later vince.
