Aero Precision AR-10 M5 308 Stripped Lower Receiver, Black

The 308 80 percent lower with jig system is an essential starting point for building a custom AR-10 platform rifle. Aero Precision’s M5 .308 Stripped Lower Receiver is crafted from 7075-T6 aluminum with a durable black hardcoat anodized finish, ensuring mil-spec compatibility and long-term reliability. Designed for DPMS-pattern components, it features an integrated trigger guard, threaded bolt catch for screw pin installation (eliminating roll pins), and a rear takedown pin detent hole threaded for a 4-40 set screw.

This stripped lower receiver is compatible with .308 Winchester/7.62 NATO calibers, making it ideal for builders seeking a robust foundation for their AR-10 project. The inclusion of a nylon-tipped tension screw enhances fitment with upper receivers, while the precision-machined dimensions guarantee proper alignment with standard DPMS 308 magazines and parts. Whether completing an 80 percent lower or assembling a full rifle, this receiver provides the necessary durability and functionality for serious firearms enthusiasts.
