We think the standard A3 upper receiver is pretty good, and hard to improve on (cosmetics don't count). 

For URF-F (Upper Receiver, FCD, Forged), there is but a single functional change we wanted which differs from the TDP spec forged upper receiver.  Specifically,  URF-F has  relief cuts/chamfers on the area above the charging handle (before 1913 rails start) for better accessibility of a flip up BUIS's sight stalk / flip up element.

URF-F is based on TDP spec forged upper receiver, it's made and modified for Forward Controls by Centurion Arms.  Type 3 hard coated in black (FDE to follow).  Like TDP spec A3 upper receivers, URF-F can accommodate a forward assist, but does not come installed with one.

URF-F can be ordered with or without a factory ejection port cover, or our EPC (billet, 7075 aluminum).
