.308 80% Lower – Billet

If you are building a precision rifle or a heavy-hitting battle rifle, the lower receiver is your foundation. The .308 80% lower – billet gives you the freedom to complete your AR-10 or DPMS-pattern build on your own terms. Machined from solid 7075-T6 aluminum, this 80% lower offers the strength and rigidity needed for larger calibers while putting the final finishing work in your hands. Whether you are a first-time builder or a seasoned hobbyist, this is a solid starting point for a custom .308 platform.

Overview

This .308 80% lower – billet is designed for shooters who want full control over their firearm’s legal manufacture. Starting as an unfinished component, it requires you to complete the fire control cavity and trigger pin holes using a jig and router or drill press. The billet construction means no casting porosity and tighter tolerances compared to forged lowers. It is compatible with DPMS-pattern upper receivers and most standard AR-10 parts kits, making it a versatile base for long-range shooting, hunting, or tactical applications.
