Aero Precision APAR501801C ReceiverMulti-Caliber 7075-T6 Aluminum Flat Dark Earth Cerakote for AR-15

The Aero Precision AR-15 multi-caliber receiver is built from 7075-T6 aircraft-grade aluminum and finished in Flat Dark Earth Cerakote for a durable, professional look that stands up to field use. This stripped upper receiver is designed for builders and shooters who want a solid foundation for custom AR builds—whether you're assembling a hunting rifle, a range gun, or a tactical platform. The 7075-T6 aluminum delivers the strength you need in a lightweight package, and the Cerakote finish resists wear and corrosion better than standard anodizing, making it a smart choice if you plan to use your rifle hard.

This receiver features M4 feed ramps, which ensure reliable feeding across standard AR-15 calibers and ammunition types. It's fully compatible with mil-spec AR-15 lower receivers and standard components, so you can build with parts from your preferred suppliers without hunting for oddball compatibility issues. The .250 takedown pin holes are machined to spec, giving you the tight tolerances that matter when assembling a rifle you trust.

If you're a hands-on builder who values quality materials and finish, the Aero Precision upper receiver delivers the kind of attention to detail that keeps your build feeling tight and looking sharp over thousands of rounds. The Flat Dark Earth Cerakote adds visual character while doing real work against the elements.

Frequently Asked Questions

Will this receiver work with my AR-15 lower receiver?

Yes. The Aero Precision upper receiver is fully compatible with mil-spec AR-15 lower receivers and standard AR components. As long as your lower meets mil-spec dimensions, they'll mate up properly.

What calibers can this receiver handle?

The M4 feed ramps on this receiver support standard AR-15 calibers and ammunition types. The receiver itself is multi-caliber—the specific caliber you build depends on the barrel and bolt you choose.

Is this receiver stripped or assembled?

This is a stripped upper receiver, meaning it comes without the bolt carrier group, charging handle, or other components. You'll need to source those separately to complete your build.

Why 7075-T6 aluminum?

7075-T6 is aircraft-grade aluminum that offers excellent strength-to-weight ratio, making it ideal for rifle receivers. It's stronger than standard aluminum alloys while keeping your upper light. The Flat Dark Earth Cerakote finish adds another layer of protection against wear and corrosion.
