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.
Our three-pack of lowers remains a popular choice among AR builders who plan on assembling numerous rifles and pistols. To save time, money, and guesswork, we threw together this bundle with the new Elite Builder Jig. Specifically designed to precisely machine multiple receivers, the Elite Builder is the perfect companion for easy builds.
(3) Forged 80% Lowers (“FIRE/SAVE” engraved)
The original forged and engraved 80% lower is our most popular receiver blank. Thousands of builders have finished their rifles and pistols with this receiver blank, constructed with a mil-spec fit and finish. The rear shelf and takedown pin are already completed, reducing overall machining time and ensuring your upper assembly fits perfectly.

The Elite Builder Jig w/ HSS Tooling
The Elite Builder goes further than most 80% jigs, providing hardened steel for the top plates and side plates instead of aluminum. This adds weight, stability, and ultimately guarantees tight tolerances for a perfectly cut and drilled receiver. The side plates’ drill bushings ensure your trigger, hammer, and safety pin holes are exactly where they need to be so your lower parts kit works flawlessly with the first trigger pull.
