Aero Precision M4E1-T Complete Upper, 16″ 5.56 Mid-Length Gov Profile Barrel, 15″ MOD 4 Handguard – Black
The Aero Precision M4E1-T Complete Upper, 16″ 5.56 Mid-Length Gov Profile Barrel, 15″ MOD 4 Handguard – Black, offers a refined balance of reliability and versatility for the AR-15 platform. This upper is factory-assembled and designed for shooters seeking a duty-grade solution with premium features out of the box. Built around Aero Precision’s enhanced M4E1 upper receiver, this configuration provides added strength and a one-piece look with the included handguard system.
At its core is a 16″ 4150 Chrome Moly Vanadium barrel treated with a QPQ Nitride finish, delivering exceptional wear and corrosion resistance. The 1:7 twist rate allows for excellent stabilization of common 5.56 NATO bullet weights, including heavier match loads and defensive rounds. The government profile maintains strength while minimizing unnecessary weight, making it ideal for duty, training, or recreational use.
The 15″ MOD 4 Handguard features a full-length top rail, M-LOK compatibility for accessory mounting, and a slim profile for improved ergonomics. Whether you’re adding lights, lasers, grips, or sling mounts, this handguard offers the flexibility and real estate to support your setup. The assembly includes a low-profile gas block and carbine-length gas system, providing consistent cycling with reduced recoil impulse.
The upper is topped with a hardcoat anodized 7075-T6 aluminum M4E1 receiver and includes a pre-installed forward assist and port door. The M4 Feed Ramp Extension ensures reliable feeding during rapid fire. Standard 1/2×28 muzzle threads allow for the installation of your preferred muzzle brake, compensator, or suppressor mount. The 11° recessed target crown enhances accuracy by protecting the barrel’s rifling at the muzzle.
This complete upper is compatible with all standard AR15 components and lower receivers. Ideal for builders who want a premium upper without the guesswork, this assembly is ready for any serious shooting application.
