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

This Eliter Build 80% Lower Jig is compatible with our Forged 80% Lowers and our Premium Fire/Safe Marked Billet 80% Lowers! Other manufacturer's billet 80% lowers may be compatible with this 80% lower jig, provided their lower receiver design adheres to mil-spec specifications.

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.
