80% Lower Fire/Safe (5-pack) & AR15/AR9 Elite Builder 80% Lower Jig with Tooling



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.

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.

Receiver Specs:

  • Type III Hard Anodized 
  • 100% Mil-Spec Fittings
  • Fire/Safe Marked: Yes 
  • Forged 7075-T6 Aluminum 
  • Broached Magwell 
  • Made in the USA 

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. This heavy anodized jig provides a more stable platform for machining, while the HSS bits and center-cut end mill provide the performance necessary to precisely finish each receiver. Make quick and easy plunge cuts to finish the fire control cavity of each receiver using any basic drill press.
