As a serialized component, this 80% lower is transferred as a non-firearm. Its 7075-T6 billet construction offers superior strength over forged receivers, particularly in high-stress areas. The integrated flared magwell and Cerakote finish are practical upgrades for a functional build. Completion requires machining the fire control group pocket and drilling the trigger pin holes using a proper jig and tools.
