Everything has sold, thanks. Got all this in a trade, I have no idea why it's painted gray. Other than handling marks, the uppers are clean and seem to be in overall good condition. Maybe they were for builds that never happened? The BCG is complete and the gas key is staked, but the small parts all have been used and I don't know who made it. The gas block may have been a take off part. US shipping only. Upper #1 is a VLTOR MUR-1s without a forward assist. Asking $75 shipped. https://www.bauer-precision.com/vltor-mur-1s-upper-receiver-free-shipping/ Upper #2 is a DPMS Lo-Pro without a forward assist. For a 5.56, this thing is beefy. Asking $45 shipped. https://www.dpmsinc.com/Flattop-Lo-Pro-Upper-Receiver_p_253.html The BCG, $25 shipped. The gas block is .750 and how about free with any other item purchased?
