Overview

Built for a .308 AR project, this assembled upper receiver provides a solid starting point for hunters and shooters assembling a DPMS pattern rifle. It is machined to Aero Precision’s specifications and includes an installed forward assist and ejection port cover, which helps simplify the build process. Compatibility with standard DPMS pattern .308 components and high profile handguards gives it a practical fit for a wide range of setups, though it is intended specifically for matching pattern parts. The hard coat anodized finish and forged 7075-T6 aluminum construction round out a receiver designed for a serious, no-frills build.

Considerations & Trade-offs

  • This is a stripped upper receiver assembly, so it still requires matching DPMS pattern .308 components and a compatible lower to complete the build.
  • Compatibility is specific to DPMS pattern .308 parts and DPMS high profile handguards, which narrows parts selection compared with more universal options.
  • The finish is matte black hard coat anodized; the provided data does not indicate an OD green finish, so color expectations should be verified against the listing.
  • At 14.1 oz, it is not a lightweight component, so builders prioritizing minimum upper weight may want to account for that in the overall setup.
