Polymer80Market Patriot Pack: Build the AR-15, AR-9, and AR-10. One Kit.
Stop deciding which 80% lower to buy first. This is the pack we recommend to builders who are serious about covering the entire AR platform. You get a genuine forged AR-15 lower, a dedicated 9mm lower for Glock mags, and a beast of a .308 lower—all for a price that makes buying them individually hard to justify.
This isn’t a random bundle. It’s the core of three distinct builds. The AR-15 lower is your classic, forged 7075-T6 mil-spec foundation. The 9mm lower is machined from 6061 billet with a reinforced trigger guard and a threaded bolt catch pin so it stays put. The .308 lower is pure heavy-duty 7075 billet aluminum, built to handle the larger frame. All three are finished in a durable black Type III hard coat anodize.
Here’s exactly what you get in the Patriot Pack:
- 1x Forged AR-15 80% Lower: 7075-T6 aluminum. Mil-spec broached magwell. Fire/Safe marked. Anodized Black.
- 1x Billet 9mm 80% Lower: 6061-T6 aluminum. Compatible only with Glock® OEM and ETS magazines. Enhanced trigger guard. Threaded bolt catch hole (pin included). Fire/Safe marked. Anodized Black.
- 1x Billet .308 (AR-10) 80% Lower: 7075-T6 aluminum. Heavy-duty trigger guard. Broached magwell. Threaded bolt catch hole (pin not included). Not fire/safe marked. Anodized Black.
All three are 100% made in the USA. You need a jig and tools to finish these. We have the kits and guides on this site if you need them.
The value is simple: you’re building your collection for less. You get the versatility to run .223/5.56, 9mm, and .308/7.62×51 NATO. Whether your next build is a precision rifle, a PCC, or a go-to carbine, you’ve already got the lower. It’s the smart way to stock up.
Patriot Pack Price: $247.49
