APF AR10 Assembled Upper Receiver - Precision-Machined, Ready-to-Install
Alex Pro Firearms
Building or upgrading an AR-10 platform rifle starts with a solid foundation, and the Alex Pro Firearms AR10 stripper upper receiver delivers the precision and durability you need for a reliable, long-range shooter. This billet aluminum upper is machined to DPMS-pattern specifications, making it compatible with LR308 components and standard AR-10 build configurations. Whether you're assembling a precision hunting rifle, a target gun, or a tactical build, a quality stripped upper is the core of consistent performance.
Alex Pro Firearms machines this upper from aircraft-grade aluminum, a material choice that balances weight savings with strength—critical for rifles you'll carry into the field or train with regularly. The billet construction ensures tight tolerances and clean lines without the porosity risks of forged components. A black Cerakote finish protects the aluminum from corrosion and handling wear, and laser-engraved T-marks reference your optic alignment and bore axis, helping you set up your rifle accurately.
The "stripped" designation means you're getting the upper receiver alone—no bolt carrier group, charging handle, handguard, or other components included. That's exactly what builders want: the freedom to spec your own parts and tailor your rifle to your exact needs. Pair it with a quality BCG and handguard, and you've got the platform for a shooter that fits your hunting, range, or tactical mission.

This is a stripped upper, meaning it includes only the receiver itself. To complete a functional upper assembly, you'll need a bolt carrier group (BCG), charging handle, handguard, and any optics or sights you plan to mount. The receiver provides the foundation; your choice of components determines the rifle's performance and ergonomics.
Yes, if your build follows the DPMS-pattern standard and uses LR308-compatible components. DPMS is one of the two primary AR-10 patterns. If you're unsure which pattern your lower receiver or other components follow, verify before ordering—DPMS and SR25 patterns are not interchangeable.
The T-marks are reference lines that align with your rifle's bore axis and help you mount and zero optics accurately. They're a machinist's aid and alignment reference, particularly useful when mounting scope rings or iron sights.
Cerakote is a ceramic-based finish designed for durability in harsh conditions. It resists corrosion, solvents, and wear from normal handling and shooting. Like any finish, it can be damaged by direct impact, but it's among the most field-proven protective coatings used on quality firearms components.
