AR-10 / .308 upper receivers — DPMS-pattern large-frame flat-tops (including Aero M5), in stripped and assembled (complete) configurations. These are the receiver only, not a barreled upper assembly. Pair with a DPMS-pattern .308 lower.

Choosing an AR-10 / .308 Upper Receiver

DPMS pattern

These are DPMS-pattern (DPMS-style) large-frame receivers, such as the Aero M5. Pair them with a DPMS-style .308 lower and components — not AR-15 or Armalite-pattern parts. Large-frame .308 also uses a larger bolt carrier group than AR-15.

Stripped vs. assembled (complete)

A stripped .308 upper is a bare receiver; an assembled (complete) upper has the forward assist and dust cover installed, but no barrel or BCG. Choose based on whether you want to install those parts yourself.

Receiver only — what you still need

This is the upper receiver, not a barreled assembly. Add a .308 barrel, handguard, gas system, large-frame BCG, and charging handle to finish it. Want it barreled? See our AR-10 Upper Build Assemblies.

Frequently Asked Questions

Are these DPMS or Armalite pattern?

DPMS-pattern. Match the upper to a DPMS-style .308 lower and parts — DPMS and Armalite aren't interchangeable.

Does this include a barrel or BCG?

No — receiver only. Add a .308 barrel, handguard, gas system, large-frame BCG, and charging handle to complete it.

Do you need an FFL to buy an AR-10 upper?

No. The upper isn't the serialized part, so it ships without an FFL. The lower is the regulated part.
