The upper was a mashup of a standard TM Recoil and a G&P A1 uppers, mixed into one via magic of LC Eng Outpost, then finished by hand with rattle cans by me, as most cerakote places advised against doing so - the finish would have been too thin and wouldn't cover machining marks, filler etc.
As a fixed carry handle fanatic, I've looked high and low for a NGRS upper before jumping on this journey a while back, as none exist.
