Forged uppers may have minor surface imperfections, these are not flaws but normal in the manufacturing process. We choose function over form, we don't attempt to remove them by sand blasting them that can result in altered dimensions.
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. In 2023, we also added another bevel in the rear
NOTE: there is an overlap of the Centurion Arms made URF-F and 2023 late summer version. The major difference is the presence of anti-rotation pin hole for the latest URF-F for HDSI, SOLGW and ZEV handguards. Centurion Arms made URF-F uppers do not have the pin hole.
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).
Machined from aluminum Forgings 7075-T6
Hardcoat Anodized per MIL-A-8625F, Type III, Class 2
URF-F does not require thermal fit, and dos not have rail numbers (otherwise known as T numbers) on top, two features we don't deem useful.
Like all FCD products, URF-F is proudly made in USA.
