The Aero Precision M5 stripped upper receiver is the foundation of a quality .308 build. Machined from 7075-T6 forged aluminum and finished in hard coat anodized matte black, this receiver delivers the precision and durability that have made Aero Precision a trusted name among .308 builders. It arrives stripped—ready for you to add barrel, bolt carrier, charging handle, and handguard according to your vision.

Built to Aero Precision's exacting standards, the M5 upper features M4 feedramps for reliable feeding and DPMS-pattern .2795" takedown pin holes that keep you compatible with the broadest selection of .308 lower receivers and components on the market. The flat-top design includes laser-engraved T-marks for easy sight reference, and the Mil 8625 Type 3 Class 2 anodize provides the corrosion resistance and durability you expect in a rifle that'll see real use—whether on the range, in the field, or in the truck.

This is a no-frills, no-compromises upper receiver for the builder who knows what they want. Pair it with a DPMS-compatible .308 lower, barrel, and bolt carrier to complete your rifle.
