Aero Precision

Elevate your AR-15 build with the Aero Precision M4E1 Stripped Lower Receiver in Anodized Black. Combining billet aesthetics with the reliability of a forged package, this custom-designed lower receiver is machined from 7075-T6 Aluminum and is compatible with all mil-spec AR15 parts.

Enhanced with both visual and functional features, the M4E1 Lower Receiver simplifies the assembly process for DIY builders. Notable features include a threaded bolt catch roll pin for easy installation, an integrated trigger guard for added strength, and an upper tension screw for a precise fit with any standard AR15 upper receiver.

The M4E1 Threaded Stripped Lower Receiver perfectly pairs with the Aero Precision M4E1 Threaded Upper Receiver, offering a billet appearance at a fraction of the cost.
