Fill up the gun safe with every AR configuration you’ve ever wanted. You’re a builder and you like to customize from scratch, so it only makes sense to start with some 80% lowers. But cutting and drilling a five-pack of receivers requires a quality, reinforced jig capable of producing consistency. That's why we threw this combo together with the Elite Builder Jig and some industrial-grade HSS bits.
(5) Forged 80% Lowers (“FIRE/SAVE” engraved)
Our forged and engraved mil-spec 80% lower is one of the market’s top receiver blanks. Built by thousands of shooters, it offers the same fit and finish you’d get on a retail stripped receiver. “FIRE/SAFE” markings come engraved, and the rear shelf with takedown pin is also completed, reducing total machining time.

The Elite Builder Jig w/ HSS Tooling
The Elite Builder Jig utilizes hardened steel top and side plates with reinforced drill bushings to allow for precise cutting and drilling of all five receiver blanks.

Make quick and easy plunge cuts to finish the fire control cavity of each receiver using any basic drill press.
