Elite Builder 80% Lower Jig – AR15/AR9

Categories: ,


This Elite Builder 80% Lower Jig is DISCONTINUED. 

Compatible with our Forged 80% Lowers and our Premium Fire/Safe Marked Billet 80% Lowers! Other manufacturers’ billet 80% lowers may be compatible with the Elite Builder 80% lower jig, provided their lower receiver design adheres to mil-spec specifications. However, we cannot guarantee that other manufacturers’ lowers, including 9mm calibers, will absolutely fit into the jig without modification unless they meet mil-spec parameters.

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.

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.

PLEASE NOTE: Tooling for this jig is optional. You’ll need to select whether you would like accompanying tooling with your jig.

Quality HSS Bits

The jig’s only as good as the bits you use it with. Choose to add on the optional tooling – quality industrial-grade HSS (high-speed steel) drill bits and end mill bits to cut through all that aluminum in no time. All you need to complete your receiver blank is a basic drill press and about two hours’ time. 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
