Aero Precision M4E1-T Complete Upper, 14.5″ 5.56 Mid-Length Gov Profile Barrel, 13.5″ MOD 4 Handguard – OD Green

The Aero Precision M4E1-T Complete Upper, 14.5″ 5.56 Mid-Length Gov Profile Barrel, 13.5″ MOD 4 Handguard – OD Green offers a highly maneuverable and visually striking upper receiver assembly for the AR15 platform. Built for duty use or recreational shooting, this configuration features enhanced components that prioritize performance, balance, and reliability.

The 14.5″ barrel is constructed from 4150 Chrome Moly Vanadium steel and treated with QPQ Nitride to improve longevity and resist corrosion. With a 1:7 twist rate, this barrel is optimal for stabilizing a wide range of bullet weights, including 62-grain M855 and other heavier match-grade loads. A mid-length gas system smooths out recoil and reduces internal wear.

The 13.5″ MOD 4 Handguard is slim, lightweight, and free-floating. It features M-LOK compatibility for mounting tactical accessories and a full-length Picatinny top rail for optics and iron sights. Whether you’re building a lightweight field rifle or a pinned-and-welded duty gun, this handguard offers rock-solid attachment and style.

The OD Green anodized M4E1 upper receiver is forged from 7075-T6 aluminum and includes a forward assist and port door. The 1/2×28 threaded muzzle allows for the attachment of suppressors or brakes, and the 11° recessed target crown preserves the barrel’s precision at the muzzle.

Designed to work with all standard AR15 lowers, this upper includes a Nickel Boron Coated M4 Feed Ramp Extension for smooth and reliable operation with a variety of ammunition types. Rugged, stylish, and ready to build, this complete upper is perfect for shooters who want a shorter rifle with standout aesthetics and professional-grade performance.
