Aero Precision M5E1 Enhanced Upper Receiver 308 Win Flat Dark Earth Cerakote

Description

Product Overview

Aero Precision’s M5E1 Enhanced Upper Receiver is a one-piece upper/handguard mounting platform built for the 308 Win AR10 pattern. The same forging serves as both the upper receiver and the free-float handguard mounting surface, helping create a rigid, consistent interface while using lightening cuts to reduce weight and support efficient cooling.

Key Features

• One-piece M5E1 integrated upper and handguard mounting platform for improved mounting consistency
• M4 feedramps for reliable AR10-style feeding geometry
• 0.2795 takedown pin holes for the intended M5E1/AR10 interface
• Laser-engraved T-marks for quick, repeatable alignment during build work
• Comes assembled with forward assist and port door installed, plus a dust cover
• Flat Dark Earth Cerakote finish for corrosion resistance and durable appearance

Drop your barrel assembly in, torque the barrel nut, and mount an Aero M5 Enhanced handguard to complete a clean, rigid M5E1 build.
