This A3 upper has seen better days. The receiver looks to have been dragged through some gravel, and some of the rail "teeth" have been sheared...not completely, as it would still be usable.
The free-float tube looks to be in "good" condition with minor scratches here and there. It has a low-profile gas block and a stainless steel bull barrel, (that actually looks quite nice)! There is no BCG or CH with this upper. This combo would make a great "beater" or truck gun. Personally, I'd replace the receiver, but that would be up to you. Price is $200.00 shipped in CONUS. Please IM me if interested.
I'll have pics up tomorrow, some time in the afternoon.
