I have this RRA M4A3 upper light under HGs with the pressed on fake flash hider for sale or trade. It comes complete with BC assy & charging handle. Not many rounds on this one due to the clean crisp bore. It does not have feed ramps yet it has an F marked front sight tower and Colt double heat shield glued fat handguards. This looks like one of the original uppers out due to the lack of T numbers on the top rail. Marked with the key hole on the receiver and the enhanced BC. The receiver and barrel have several ilght scratches from range use but nothing to worry about. If I had to say there is less than 500 round through it.
