Aero Precision APAR308505AC Assembled Receiver 308 Win 7075-T6 Aluminum Flat Dark Earth Cerakote Receiver for M5 Platform

The Aero Precision APAR308505AC Assembled Receiver for the M5 platform serves as the foundation for a precision .308 Winchester rifle build, trusted by law enforcement marksmen, military armorers, and competitive shooters. This fully assembled upper receiver eliminates the guesswork of component integration, delivering a combat-proven platform optimized for accuracy and reliability in demanding tactical environments.

Machined from 7075-T6 aluminum alloy and finished in Flat Dark Earth Cerakote, the Aero Precision receiver combines ballistic-grade material strength with corrosion resistance suited for field deployment. The 7075-T6 forging provides superior durability compared to standard 6061 aluminum, maintaining structural integrity under sustained fire and harsh environmental conditions. The precision-cut M5 platform interface ensures zero tolerance stacking with Aero Precision lower receivers and compatible components.

Professional gunsmiths and DIY builders benefit from the pre-assembled construction, which means proper headspacing geometry and critical tolerances are already validated. This eliminates assembly variables and reduces time-to-range on your build. The Flat Dark Earth coating provides a non-reflective finish that blends seamlessly into modern tactical loadouts.
