Elite Builder 80% Lower Jig with Tooling - AR-15/AR-9



Elite Builder’s 80% jig is the unit you need to buy if you’re ready to machine multiple 80% lowers for the AR-15 and AR-9. This jig-and-tooling combo kit includes high-quality HSS bits and a precisely tuned jig built from hardened steel plates - not softer aluminum, like some other jigs. The result is a gunsmithing workstation capable of chewing through any billet, forged, or polymer receiver blank in no time at all.

Drill Bits & End Mill Bits Included

The HSS (high-speed steel) bits included with the Elite Builder 80% Lower Jig are specially designed for cutting and drilling 6061-T6 and 7075-T6 aluminum. Work on a receiver can be 100% completed in under two hours with little more than a basic drill press and some cutting fluid. The tool kit includes:

  • (1) ⅜ Drill Bit - 5”
  • (1) 5/32 Drill Bit - 3”
