308 80% LOWER RECEIVER AND JIG SYSTEM – GRAY

The 308 80% Lower Receiver and Jig System – Gray brings an ultralight, reinforced design to the DPMS‑pattern .308 platform. Inspired by modern polymer firearm technology, this system uses a high‑strength, weapons‑grade polymer blend to cut weight while maintaining dependable structural integrity.

This receiver weighs under half a pound, giving shooters a dramatically lighter foundation compared to traditional aluminum AR‑10‑style components. Its reinforced construction includes a solid‑core interior, strengthened buffer tube ring, ribbing along the upper edges, and a stiffened magwell. These improvements enhance durability while preserving the featherweight feel that defines the design.

The included 80% lower jig, pistol‑grip hardware, and essential tooling support lawful personal‑build projects. The integrated trigger guard and ergonomic gripped magwell help improve handling and comfort. Designed for DPMS Gen 1 compatibility, the system provides a resilient, lightweight option for builders seeking performance and maneuverability.
