Aero Precision M4E1-T Complete Upper, 11.5″ 5.56 Mid-Length Gov Profile Barrel, 10.6″ MOD 4 Handguard – OD Green
The Aero Precision M4E1-T Complete Upper with 11.5″ 5.56 Mid-Length Government Profile Barrel and 10.6″ MOD 4 Handguard in OD Green is a performance-driven choice for short-barreled rifle or AR-15 pistol builds. Designed with durability, modularity, and aesthetics in mind, this upper delivers optimal functionality in close-quarters applications, home defense setups, or professional-grade tactical builds.
At the heart of this complete upper is a 4150 Chrome Moly Vanadium barrel with a QPQ Nitride finish, engineered to enhance barrel longevity and corrosion resistance. The 1:7 twist rate supports heavier bullet weights, making it suitable for 62gr green tip or 77gr precision match loads. A carbine-length gas system ensures dependable cycling whether the system is suppressed or run bare, while maintaining smooth recoil impulse.
The 10.6″ MOD 4 Handguard is built from durable aluminum and features full-length M-LOK compatibility and a continuous Picatinny rail for maximum accessory mounting flexibility. Its free-float construction boosts barrel accuracy while the ergonomic OD Green finish adds visual contrast for shooters looking to stand out from the standard black configuration. The slim profile handguard also enhances grip and handling during dynamic movement or extended use.
This upper features Aero Precision’s enhanced M4E1 receiver forged from 7075-T6 aluminum, integrating a factory-installed forward assist and port door. The Nickel Boron-coated M4 feed ramp extension offers smooth chambering and extended durability. The muzzle is threaded 1/2″x28 and finished with an 11° recessed target crown, preserving both accuracy and barrel life while allowing easy suppressor or muzzle device installation.
Compatible with any mil-spec AR-15 lower receiver, the Aero Precision M4E1-T Upper is a go-to choice for those seeking a compact, rugged solution with advanced finish and build quality. Whether you’re crafting a clean-running gas system for suppressed use or looking to build a custom OD Green upper with match-grade potential, this upper brings Aero Precision’s commitment to function and form to the forefront.
