This Elite Builder 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.
The fast, accurate, bombproof 80% Lower Jig from Elite Builder now ships with equally high-quality drill bits and end
mill bits. This gunsmithing combo kit allows you to confidently cut and drill multiple AR-15 and AR-9 80% lower receivers without losing speed or accuracy.
