The APF AR10 assembled upper receiver from Alex Pro Firearms is a complete, ready-to-run upper assembly built for shooters who want precision machining without the assembly headaches. If you're building an AR-10 platform rifle—whether for long-range hunting, match competition, or precision rifle work—this billet upper gives you a professional-grade foundation that's already gone through the bench work. It ships fully assembled with forward assist and dust cover installed, so you can focus on pairing it with your lower and getting to the range.
Machined from billet aircraft-quality aluminum, this upper is built tough enough for serious use. The Cerakote finish handles field conditions and protects against corrosion, while laser-engraved T-marks give you consistent sight references. The included T-handle charging handle gets you into battery smoothly, and the ejection port cover keeps debris out when you need a clean rifle.
DPMS-pattern and LR308-compatible, this upper will mate with standard AR-10 lower receivers, making it a straightforward swap for builders who already have a lower or are sourcing one separately. Whether you're upgrading an existing platform or starting fresh, an assembled upper like this cuts weeks off your build timeline and eliminates fitment guesswork.

The APF AR10 upper is compatible with DPMS and LR308 pattern AR-10 lowers. If your lower is built on either of those platforms, this upper will install without fitment issues.
This upper assembly ships fully assembled with the forward assist, ejection port cover, and T-handle charging handle already installed. You'll be ready to mount it on your lower and configure your rifle.
Billet uppers are machined from solid aluminum stock, allowing tighter tolerances and more precise manufacturing. They're excellent for precision rifle builds where consistency matters, though they generally weigh slightly more than forged alternatives.
