Aero Precision M5E1 (.308) Enhanced Upper Receiver

Aero Precision M5E1 (.308) Enhanced Upper Receiver

The state-of-the-art M5E1 platform starts here, with the M5E1 Upper Receiver. The M5E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself.

Ease of installation – Insert your barrel assembly into the M5E1 upper, tighten it using the included barrel nut, and slide your rail on and tighten the rail screws. Within minutes, you have a modular, free-floated rail.
