An AR-10 80% lower receiver is the unfinished foundation of a .308 / 7.62 build. Like its AR-15 counterpart, it needs final machining — the fire-control pocket, trigger slot, and pin holes — before it becomes a functional receiver, which is what makes it the starting point for a custom .308 rifle. Most of our .308 lowers are DPMS pattern; pair one with a DPMS-pattern upper and a .308 lower parts kit to complete the build.

Daytona Tactical stocks forged, billet, and polymer 80% .308 lowers in raw aluminum and a range of Cerakote finishes — including FDE, OD green, burnt bronze, tungsten grey, and several colors — along with polymer-and-jig systems and 80% lower + stripped upper sets.

Choosing an AR-10 / .308 80% Lower Receiver

Building a .308 from an 80% lower gives you control over the rifle while saving on the receiver. For AR-10-platform builds there are three things worth understanding before you buy: the receiver pattern, the manufacturing method, and whether a jig is included.

DPMS vs. Armalite pattern (read this first)

Unlike the AR-15, the AR-10 platform isn’t fully standardized. There are two main patterns — DPMS (also called .308 / “high profile”) and Armalite (AR-10A) — and they are not cross-compatible. The upper, lower, and many parts must match the same pattern. The large majority of .308 parts and uppers on the market today, including ours, are DPMS pattern, so a DPMS lower pairs with a DPMS upper. Confirm your other components are DPMS pattern before completing a build with one of these lowers.

Billet, forged, or polymer

Forged lowers are pressed from heated aluminum — strong, consistent, and economical. Billet lowers are CNC-machined from solid aluminum, allowing more styling at a higher price. Polymer 80% lowers (often sold as a system with their own jig) are the lightest and least expensive route.

All accept standard DPMS-pattern .308 parts; the choice comes down to budget, weight, and looks.

With or without a jig

Completing an 80% lower requires a jig to guide the drilling and milling. Some of our listings are polymer-and-jig systems or include a jig; standalone aluminum lowers assume you already have a compatible jig. Check the listing before ordering.

Features that vary by model

Some — not all — of our .308 lowers add features beyond the basics, such as flared magwells or enhanced trigger guards. Each product page lists its specific material, finish, pattern, and whether a jig or matching upper is included. Color and Cerakote options vary by model.

Building it out

To finish a .308 build you’ll pair the lower with a DPMS-pattern complete or stripped upper, a .308 lower parts kit, and a stock assembly. We also offer 80% lower + stripped upper sets that keep the pattern matched for you. Browse our .308 uppers and lower parts kits to match components to your project.

Frequently Asked Questions

What’s the difference between DPMS and Armalite AR-10 patterns?

The AR-10 platform has two main, non-interchangeable patterns: DPMS (.308, the most common today) and Armalite (AR-10A). Uppers, lowers, and many parts must share the same pattern. Most current .308 components, including ours, are DPMS pattern. Always match your upper and lower to the same pattern.

Is an AR-10 80% lower the same as an AR-15 80% lower?

No. AR-10 / .308 lowers are larger and built for the 7.62×51 / .308 cartridge, and they use .308-specific parts. An AR-15 80% lower and an AR-10 80% lower are not interchangeable.

What do I need a jig for, and is one included?

A jig guides the drilling and milling needed to finish the receiver. Some of our .308 listings — particularly the polymer systems — include a jig; standalone aluminum lowers assume you already have a compatible one. Check the specific product page.

Do you need an FFL to buy an 80% lower receiver?

It depends on how the item is sold and where you live. Following the 2025 U.S. Supreme Court decision in Bondi v. VanDerStok, certain partially complete receivers — particularly those sold as kits with a jig and the parts needed to readily complete them — can be treated as firearms, meaning they must be serialized and transferred through a licensed dealer. Individual unfinished lowers sold without a kit are often handled differently. Because the rules turn on these details

and continue to evolve, confirm the current federal requirement and how a specific product ships before ordering.

Are 80% lowers legal in my state?

Federal and state law are separate, and state law on unfinished receivers and self-built firearms varies widely — some states restrict or prohibit them, while others allow personal builds with little oversight. Check the current law in your own state before purchasing. This page is general information, not legal advice.
