Elite Builder 80% Lower Jig (AR-15/AR-9)

The fast, accurate, bombproof 80% Lower Jig from Elite Builder now ships with equally high-quality drill bits and end mill bits. This gunsmithing combo kit allows you to confidently cut and drill multiple AR-15 and AR-9 80% lower receivers without losing speed or accuracy. Hardened steel template plates and a self-aligning design make machining quick and free of guesswork. Thanks to its reinforced design, the Elite Builder jig can reliably handle any polymer, billet, or forged 80% lower with a standard (mil-spec) configuration. You can also now choose to include the enhanced drill plate to further make it easier for you to drill and hollow out your fire control group pocket. This jig is compatible with lowers that meet mil-spec dimensions.
