Specs at a glance
About this product
If you’re building a 9mm AR pistol or rifle, the F-1 Firearms UX-9 upper receiver is a solid choice for shaving weight and improving handling. We carry this in stock here in Wichita for local pickup, and ship to other Kansas addresses when legal.
What the F-1 UX-9 Does for Your AR
This isn’t about fancy features, it's about a well-made component that performs. The skeletonized design removes unnecessary material, making your 9mm AR lighter and easier to maneuver – useful whether you’re moving through a home defense situation, or spending a day at the range. The open structure also helps dissipate heat faster, which keeps things running consistently when you’re putting rounds downrange.
Key Features:
- Lightweight: Skeletonized aluminum reduces overall weight.
- Cooling: Improves heat dissipation during rapid fire.
- Compatibility: Works with standard AR-15 lower receivers chambered in 9mm.
- Finish: Matte black finish.
