Product Summary
The Aero Precision M4E1 Stripped Lower Receiver combines the look of a billet receiver with the strength of a forged 7075-T6 aluminum build. It is designed for full compatibility with all mil-spec AR-15 parts and features a black hardcoat anodized finish. Key upgrades include an integrated, enlarged trigger guard for glove use and a flared magazine well for faster reloads. Additionally, an upper tension screw is included to eliminate rattle between the upper and lower receivers, making it an ideal foundation for a custom high-performance build.
