80% Lower Patriot Pack

The Patriot Pack: Build the AR-15, AR-9, and AR-10. No Compromises.

You shouldn’t have to pick just one. The AR platform’s genius is its versatility, and our Patriot Pack delivers it. This bundle gives you a genuine, serialized 80% lower for the three most popular builds: the classic 5.56/.223 AR-15, the hard-hitting .308 AR-10, and the affordable-funning 9mm AR-9. It’s the smart way to build your collection.

We don’t cut corners. The AR-15 lower is forged from 7075-T6 aluminum, just like the military spec. It’s tough, light, and has a broached magwell for perfect magazine fit. The 9mm lower is machined from 6061-T6 billet with a reinforced trigger guard and uses reliable Glock-pattern mags. The .308 lower is built from heavy-duty 7075-T6 billet to handle the bigger round, featuring a robust trigger guard and broached magwell. All three are made right here in the USA, finished in a durable black hardcoat anodize.

This pack is for builders who know the details matter. The 9mm lower includes a threaded bolt catch pin for a clean install. The AR-15 and 9mm are fire/safe marked for a finished look. The .308 lower is left blank for your custom markings. You’re getting three premium, purpose-built lowers for what you’d typically pay for two. It’s the most efficient way to start your next three projects without waiting.
