New Release: MP5 80% Lower Patriot Pack

Just released for 2026. One of our newest catalog additions. Fully in-stock, shipping now.

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!
