Aero Precision M5 Stripped Upper Receiver – AR10/.308, Black Anodized

The Aero Precision M5 Stripped Upper Receiver in black anodized (brand part no. APAR308503C) is machined for the AR10/.308 platform, forged from 7075-T6 aluminum for durability under the heavier recoil of .308-class cartridges. Aero Precision precision-machines the receiver to accept standard .308 (M5-pattern) components, with M4 feed ramps for reliable feeding straight out of the box. As an upper receiver, it is not the ATF-serialized part of the rifle — that distinction belongs to the lower receiver — so it ships and installs like any other Title I AR part. It is sold stripped, ready to accept a compatible barrel, bolt carrier group, and charging handle.
