80% Lower Patriot Pack

Build all three ARs with one 80% lower combo kit.
Originally chambered in 5.56 NATO and .223 remington, the AR has evolved to chamber different calibers, with upper and lower receivers redesigned to include the .308 AR-10, and the 9mm AR9. It can be hard to choose a favorite. So, don’t settle — just grab this bundle of 80% lowers for every AR platform!

.308 Receiver & Parts Kit Compatibility
Due to the varying quality and compatibility of .308 builds, we recommend using our LR-308/AR-10 Lower Parts Kit. This lower parts kit includes the correct bolt catch threaded pin, too, which makes install a breeze.
Assembling Your 80% Lowers
Once each lower is fabricated, it’s time to assemble it. For each build (AR-15, AR-10, and AR9) You’ll need the following components, available below. Make sure to filter by the platform when selecting each component for each type of receiver.
