Aero Precision M4E1 Pro Complete Lower Receiver

The Aero Precision M4E1 Pro Complete Lower Receiver is a premium foundation for building a high-quality AR-15, offering unmatched durability and compatibility with a wide variety of uppers. Aero Precision’s new Pro line is a new level of performance and fine machining with every little detail being considered and addressed.

An ambidextrous safety, bolt catch/release, and safety selector lets users with either dominant hand easily manipulate the controls of the weapon for even faster function. The M4E1 Pro Complete Lower comes assembled from the factory, enabling users to add on their custom uppers with the click of two pins. Additionally, this lower comes with the tried and true Magpul MOE Pistol Grip and SL Stock for even more comfort and ergonomics.

Crafted from 7075-T6 forged aluminum, the M4E1 Pro combines the strength of a traditional forged lower with the sleek aesthetics and enhanced features of a modern design. Its integrated trigger guard and flared magazine well improve ergonomics and functionality, making reloads faster and more efficient. The receiver’s anodized finish ensures superior resistance to corrosion and wear, maintaining its appearance and performance even under heavy use.

Whether you’re building a tactical carbine, competition rifle, or all-purpose firearm, this lower receiver provides the reliability and precision you demand.
