Bought this upper from another hide member here. It got a WOA 18" SPR barrel, BCM quad rail, Bushmaster upper w/ BCG/CH, and a superlative adjustable gas block. It needs a brake/flush hider. Round count <700 by its original owner. I took it on one range trip and it's a good shooter. The collar on the barrel is a look-alike, not the original Allen Engineering collar. I spray-painted the front part of the barrel and the rail panels due to some paint scratch so the color is slightly mismatched. Selling things I don't regularly shoot, and hope someone can find a good use of this upper.
$500 $450 shipped.
