How to Finish Your 80% Lowers

Cutting and drilling your 80% lower to make it functional requires an AR-15 jig. We recommend the Elite Builder Patriot Jig, available here -- it's capable of finishing all three lowers included in this bundle. Follow these detailed, step-by-step instructions to fabricate your 80% lower using the Elite Builder Jig.

Assembling Your Lowers

Once your lowers are fabricated, it's time to assemble them. You'll need AR-type lower parts kits, available here, and  buffer tube kits for each receiver. Follow our step-by-step picture guide for installing your lower parts kits and buffer assemblies.
