The Elite Builder 80% Lower Jig and tool kit combo is the key to cutting and drilling multiple 80% lower receivers for the AR-15 or AR-9 without losing efficiency or accuracy. Made from hardened steel plates, the Elite Builder jig can machine any standard (mil-spec) forged, billet, or polymer receiver without breaking a sweat, with results as accurate as one-thousandth (0.001”) of an inch.
Includes Quality HSS Bits
The jig’s only as good as the bits you use it with. So, the Elite Builder includes quality industrial-grade HSS (high-speed steel) drill bits and end mill bits to cut through all that aluminum in no time.
