.308 80% Lower – Billet

When you are building a precision rifle or a heavy-hitting battle rifle, the foundation matters. The .308 80% lower – billet is where your project begins. Machined from solid 7075-T6 aluminum, this lower receiver gives you the platform to craft a firearm that is truly yours. Whether you are assembling a long-range setup or a reliable hunting rig, this billet component offers the rigidity and dimensional accuracy that a .308 build demands. We have worked with enough raw receivers to know that the difference between a good build and a great one often comes down to the starting block. This one is built right.

Overview

The .308 80% lower – billet is designed for the builder who values strength and precision over shortcuts. Unlike forged receivers, which are pounded into shape, this billet lower is cut from a single block of aluminum. The result is a part with tighter tolerances and a straighter grain structure. It is compatible with DPMS-pattern .308 components, giving you a wide range of aftermarket options for triggers, stocks, and buffer systems. This is not a generic blank. It is a carefully machined platform that requires your finishing work to become functional.

Features & Specs

• Material: 7075-T6 aluminum billet, hard coat anodized for wear resistance
• Pattern: DPMS Gen 1 compatible, accepts standard .308 LPK and buffer tube assemblies
• Finish: Type III Class 2 black anodized with a matte texture for low glare

This .308 80% lower – billet includes a flared magazine well for faster reloads and a threaded bolt catch pin for easier installation. The trigger pocket is cut to accept standard AR-10 triggers, and the rear takedown pin detent hole is pre-drilled. All critical pin locations are marked for easy reference during finishing. The weight is approximately 11.5 ounces, making it solid without being overly heavy for a field rifle.

Who It's For

This part is for the hands-on builder who wants control over their rifle's final specifications. If you have a mill or a jig setup and the patience to finish the fire control pocket, this .308 80% lower – billet is your starting point. It is also ideal for the shooter who wants a dedicated lower for a specific caliber or barrel length without buying a complete factory receiver. Whether you are a weekend machinist or a seasoned gunsmith, this lower gives you the raw material to build a .308 that fits your exact needs. It is not for someone looking for a drop-in solution. It requires work, but that work pays off in a rifle that performs exactly how you want.

Shipping & FFL

Because this is an 80% lower receiver, it is not considered a firearm by the ATF. It can be shipped directly to your home or business without going through a Federal Firearms License (FFL) holder. No background check is required for purchase. However, once you complete the machining and turn it into a functional receiver, you are responsible for complying with all federal, state, and local laws regarding firearm ownership. We recommend checking your local regulations before ordering. Some states and municipalities have specific restrictions on 80% lowers. We ship via USPS or UPS with tracking and signature confirmation. If you have questions about compatibility or finishing, reach out. We build these ourselves and can give you straight answers.
