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.
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.
