80% Lower Patriot Pack

The Patriot Pack: Build Your AR Trifecta. One Kit, Three Platforms.

Why choose one AR platform when you can master them all? The Polymer80Outlet Patriot Pack solves the debate. This isn’t just a bundle; it’s your foundation for the three most essential builds in your safe. Get the forged AR-15 lower, the dedicated 9mm Glock-mag lower, and the robust .308 AR-10 lower—all in one go, for one serious price.

We put this pack together for builders who don’t do things halfway. You know that each platform has a specific purpose, and each deserves a receiver engineered for the task. Using a flimsy adapter in a standard lower is a compromise. This pack eliminates that. You get three purpose-built, American-made 80% lowers, ready for your craftsmanship.

What You Get: No-Nonsense Specs

1x Forged AR-15 80% Lower (5.56/.223)
The backbone of American rifle building. Made from forged 7075-T6 aluminum with a broached mil-spec magwell. It’s the standard for a reason. Anodized black, fire/safe marked, and ready for your favorite jig.

1x Billet 9mm 80% Lower (Glock® Magazine Compatible)
Built specifically for reliability with Glock® OEM and ETS mags. Machined from 6061-T6 billet aluminum, it features an enhanced trigger guard and a threaded bolt catch hole (pin included). No more walking pins. Type III hardcoat anodizing stands up to the rigors of a blowback system.

1x Billet .308 / AR-10 80% Lower
The heavy hitter. Machined from solid 7075-T6 aluminum billet to handle the .308 Winchester / 7.62×51 NATO platform. Features a heavy-duty trigger guard, broached magwell, and a threaded bolt catch hole for a solid build. Built tough for the big round.

Built Here, Built Right

Every lower in the Patriot Pack is 100% manufactured in the USA from aircraft-grade aluminum. These are serious blanks for serious builders. You supply the tools, the time, and the vision—we supply the uncompromising foundation.

This pack represents significant savings over buying each lower individually. It’s the smart move for the builder looking ahead. Cover your bases for a home-defense carbine, a pistol-caliber range toy, and a long-distance hunter or DMR. Your next three projects start right here.
