The .308 80% Lower – Billet comes complete with essential parts as described: .308 80% Lower – Billet When you are building a precision long-range rifle or a heavy-hitting battle rifle, the foundation matters more than any other single component. The .308 80% lower – billet is the starting point for builders who want a rigid, mil-spec compatible platform without the paperwork of a serialized receiver. Machined from a solid block of 7075-T6 aluminum, this lower gives you the stiffness needed to keep groups tight and the flexibility to finish it with basic tooling. Whether you are assembling a DPMS-pattern .308 or a 6.5 Creedmoor, this billet 80% lower is the smart choice for a custom build that stays entirely under your control. Overview This .308 80% lower – billet is designed for the AR-10 / LR-308 platform and comes as an unfinished forging. It has no serial number, which means you can complete it at home without an FFL transfer until it is machined into a functional firearm. The billet construction eliminates the porosity and stress points found in cast lowers, giving you a receiver that holds zero and resists flex under heavy recoil. Every pocket and trigger slot is pre-cut to DPMS specs, so you can drop in your preferred LPK and buffer system with minimal fitting. It is a true blank canvas for the serious builder. Features & Specs From the reinforced front takedown lug to the oversized trigger guard, this .308 80% lower – billet is built for durability and ease of finishing. The 7075-T6 aluminum is hard-coat anodized inside and out, providing a corrosion-resistant surface that accepts standard AR-10 parts without modification. The integrated rear shelf is already profiled for a standard carbine or rifle buffer tube, and the bolt catch pocket is fully machined to accept any DPMS-spec catch.

If you have a drill press, a vise, and a steady hand, you can complete this lower in an afternoon. It is ideal for builders who plan to run a heavy barrel, a suppressor, or a high-reticle scope—the billet stiffness keeps everything aligned. It is also a solid choice for anyone who wants to avoid a paper trail on their .308 build, as long as they comply with all state and local laws. This is not a beginner project if you have never completed an 80% lower, but with basic mechanical aptitude and a good jig, it is absolutely doable. Experienced builders seeking a rigid, non-serialized .308 platform Hunters and precision shooters building a lightweight .308 or 6.5 Creedmoor Anyone who prefers the stiffer feel and tighter tolerances of billet over forged Builders who want full control over finish, coating, and final fit Shipping & FFL This .308 80% lower – billet ships directly to your doorstep with no FFL transfer required because it is not yet a firearm.
