Overview

Built for a custom .308 AR foundation, this stripped lower receiver is intended for hunters and shooters assembling a big-bore rifle around compatible DPMS pattern components. Its mil-spec dimensions are designed to support correct component interface, and it accepts Gen 1 DPMS .308 magazines and upper receivers. The integrated trigger guard, threaded rear takedown pin detent hole, and threaded bolt catch pin setup simplify assembly details while keeping the receiver focused on a clean, purpose-built build. Finished in matte black hard-coat anodized Mil 8625 Type 3 Class 2, it offers a straightforward starting point for a tailored rifle project without extra features.

Considerations & Trade-offs

  • This is a stripped lower receiver, so it is only one part of a complete build and will require compatible upper receiver, magazine, and other components to finish the rifle.
  • It is specified for Gen 1 DPMS .308 components, so compatibility should be verified carefully before purchase if your build uses a different pattern or generation.
  • The receiver is finished in matte black hard-coat anodized Mil 8625 Type 3 Class 2, which may not match every other component in an ODG Cerakote build.
  • Integrated trigger guard and threaded bolt-catch/rear takedown pin features can simplify assembly, but they also lock the build into this receiver’s specific interface choices.
