Looking to build a very low budget AR-15. I need a complete A2 upper - rear sights, forward assist, everything except for the bolt and carrier and barrell assy. I do not care about the company who made it and do not care much about the cosmetic finish. It just must be functional. I am on a strict budget and cannot offer a dime over $70 shipped. I can budget for $80 if charging handle is included. Let me know if you have anything to offer.
