I recently acquired an AR in a trade. It is a beautiful piece. Here are the specs: Stag lower with 6 position collapsable stock Rock River Arms heavy barrel upper (16") 1/9 twist, with mid-length hand guards. Black hawk tac sling on a single-point mount Rock River Elite Tactical carry handle rear sight Tac Force padded trunk case I was just curious how much this item would be worth? I would have to rate it about 99%. It is LNIB. Approximately 500-700 thru it. The guy I traded with bought the upper & lower fully assembled (at different times) and put the two together. no scratches on it anywhere. Nice gun! I am not looking to sell it, just curious how much it should be worth. Any helpful input is appreciated. Thx. Be safe.
