Polymer80Buy Patriot Pack: Build the AR-15, AR-9, and AR-10. One Kit, No Compromise.
You shouldn’t have to pick just one. The Patriot Pack from Polymer80Buy solves that. This isn’t just a parts kit; it’s your foundation for three distinct builds. Get a forged AR-15 lower, a dedicated 9mm lower, and a robust .308 lower—all as 80% receivers. This pack is for the builder who knows the platform’s versatility and wants to own it all.
Here’s exactly what you get:

Why This Pack Makes Sense: Buying these lowers individually would cost you more. We bundled them because they’re the three most in-demand platforms. The 5.56/.223 AR-15 is your cornerstone. The 9mm lower gives you a common-caliber pistol or PCC. The .308 lower is for when you need serious reach and power. Each is precision-machined from top-grade aluminum, ready for your jig and tools.
A Quick Note: These are 80% lower receivers. They require machining to complete and are intended for personal use by individuals who can legally own a firearm. You are responsible for complying with all federal, state, and local laws. Final price: $247.49</
