Aero Precision M4E1 Assembled Upper Receiver in Kodiak Brown

In the realm of modern sporting rifles, precision and reliability are paramount. Enter the M4E1 Threaded Upper Receiver, a product that stands as a testament to innovative engineering and functional design. Forged from high-strength 7075-T6 Aluminum, this upper receiver promises durability without compromise.

What sets the M4E1 apart is its distinctive angular machined design—a feature that not only enhances aesthetics but also provides practical benefits in terms of weight distribution and structural integrity. This model shares its enhanced body profile with Aero Precision's M4E1 Enhanced Upper Receiver, yet it goes one step further by being threaded to accommodate a standard AR15 barrel nut.

Compatibility remains at the heart of its construction; it's precision-machined to integrate seamlessly with all mil-spec AR15 components. This ensures versatility for builders seeking both performance and customization in their builds.

For added convenience, Aero Precision has pre-installed both the port door and forward assist—details often overlooked but crucial for maintaining operational readiness under various conditions.

Whether you are an enthusiast crafting your ideal rifle or a professional demanding excellence from every component, the M4E1 Threaded Upper Receiver offers an exceptional foundation upon which to build.
