Aero Precision M5E1 Enhanced Upper Receiver – .308 Win, Flat Dark Earth

The Aero Precision M5E1 Enhanced Upper Receiver (brand part no. APAR308506AC) is a one-piece upper built for the M5 platform in .308 Winchester/7.62 NATO, finished in flat dark earth Cerakote. Aero combines the handguard mounting platform with the upper itself, condensing the parts needed to attach a free-floated handguard down to just eight screws. The receiver is machined from 7075-T6 aluminum with M4 feed ramps, 0.2795-inch takedown pin holes, and laser-engraved T-marks, and it ships assembled with the port door and forward assist already installed. This M5E1 upper is designed specifically for Aero’s M5 Enhanced Handguards and will not work with other AR10/.308 handguards. Built by Aero Precision, it still needs a charging handle, barrel, handguard, gas block, muzzle device, gas tube, and bolt carrier group to complete.
