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.
A three-pack of 80% lowers is perfect. Face it, you’ll want to build more than just one AR. Keep one for “SHTF”, use another for practice if you’re a first-time builder. Or build three rifles or pistols. The only way to cut and drill all three reliably is with an industrial-grade jig like the Elite Builder, included with quality HSS bits.
(3) Forged 80% Lowers (“FIRE/SAVE” engraved)
The forged and engraved 80% lower is one of our first-ever products to market. It’s been utilized by thousands of builders to piece together quality, mil-spec ARs in 5.56, .223, and 300 BLK with a truly custom setup, from scratch. “FIRE/SAFE” markings are already engraved and the rear shelf with takedown pin hole is completed to reduce total machining time and sure your upper assembly fits the way it should.
