Description

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”
• (1) ⅜ Short End Mill – 3”
• (1) 5/16 Short End Mill – 4”
• (1) ⅜ Long End Mill – 4”

Jig Features & Specs:

• Self-aligning jig requires no special fitting during setup
• Compatible with any standard AR-15 or AR-9 80% lower
• Black anodized finish protects against rust and corrosion
• Pre-drilled holes for hammer, trigger, and safety pin holes
• Reinforced steel template plates for completing multiple lowers
