The F-1 UDP-9 Skeletonized Upper Receiver; Designed to cosmetically flow directly into our new ultralight P7 Rail System, is now available as a complete upper half. Designed specifically for PCC, our Upper Receiver maintains the design and flow F-1 is expected to deliver. We then took it a step further and flared the front end of the Upper to compliment the lines in the newly designed P7 Rail. The Complete upper comes standard in multiple barrel lengths, and includes QC10 BCG, Ambidextrous Raptor Charging Handle, the P7 Rail System (available in 5”, 7”, and 13” lengths), and the F-1 SLAY-AR Muzzle Brake. The Complete Upper is designed for F-1 Firearms and QC10 lower receivers, but is compatible with most PCC lowers on the market up to and including 10mm variants.
- Weight and length will vary based on component selection.
