How to Complete an 80% Lower with a Drill Press Jig

In this instructional video, we're walking you through how to drill and cut the fire control cavity and pin holes on a mil-spec AR-15 80% lower, transforming it into a stripped lower receiver that's ready for a parts kit install. To complete this 80% lower, we're using a Wen 4210T Drill Press and drill press vise. We're also using our AR-15 / AR9-compatible Elite Builder Jig with the optional Enhanced Drill Plate add-on.
