Aero Precision M5 .308 Assembled Upper Receiver, FDE Cerakote

The Aero Precision M5 assembled upper receiver (Aero Precision part number APAR308505AC) is forged from 7075-T6 aluminum and precision machined to accept standard .308/7.62 NATO components, making it a strong foundation for a big-bore AR10-pattern build. Finished in Flat Dark Earth Cerakote, it ships with the port door and forward assist hardware already installed, saving builders a step during assembly. It is optic-ready with no iron sights included, and it is sized to DPMS-pattern specifications for drop-in compatibility with standard M5-platform parts. Note that a barrel, handguard, gas block, gas tube, muzzle device, charging handle, and bolt carrier group are still needed to complete the upper.
