under 700 now thats gonna be a tough one besides a cheap bushy with no sights for 750 or so. Theres a web site called Rguns.net, Welcome to the RGUNS Internet Storefront. They have cheap good quality uppers and then buy a decent cheap lower for 100-200 bucks. In total if you can find a cheap built lower than you can have a USA made AR for 700 or less depending on what type up upper,lower and parts you buy. I hope this helps.
