Overview
Built for assembling a custom .308 AR from the ground up, this stripped lower receiver is intended for builders working with Gen 1 DPMS pattern components, including compatible magazines and upper receivers. Its mil-spec dimensions are paired with a hard-coat anodized finish, and the receiver is machined from 7075-T6 aluminum. Practical details such as the threaded rear takedown pin detent hole, threaded bolt catch pin, integrated trigger guard, and selector markings support a clean, purpose-driven build. It is a straightforward foundation for a big-bore AR project, with compatibility focused on the specified DPMS pattern parts.

Considerations & Trade-offs
- Requires Gen 1 DPMS .308 components, so compatibility is narrower than a universal lower receiver.
- Sold as a stripped lower receiver, so it is only the starting point for a custom build and still requires additional parts.
- The integrated trigger guard is fixed, which removes the option to swap to a different guard style later.
- Selector markings are set up for 45, 60, or 90 degree safety selectors, so builds using other selector configurations are outside the stated fitment.
