Introducing a proper, professional-grade 80% drill press jig: The Juggernaut Tactical AR-15 Adjustable Universal Jig.

Simple Setup, Perfect for Beginners
Simply secure your billet or forged lower between the two side plates using the provided hex bolts. Secure the first top plate, and you’re ready to go. Setup takes less than five minutes and with a little patience, you’ll have a stripped lower receiver ready for your AR-15 or AR-9 in one to two hours.
The Juggernaut Drills and Cuts for You
The Juggernaut Jig is perfect for beginners and pros alike. The include top plate templates act as guides for your drill bits and end mill bits while you make your pilot holes and cut, so there are no calculations to make. To use the Juggernaut Jig, all you need is a mill or drill press with a basic depth gauge. Grab some machining oil or lubricant to keep your bits and receiver clean while you work, and the jig will do the rest! Since drill presses aren’t designed for milling, the pilot hole template plate removes most aluminum in the fire control cavity with vertical pilot holes. This allows you to safely mill out what little aluminum remains without exerting force on your drill press’s chuck.
