Multi-Platform Jigs

WHAT IS AN 80% MULTI-PLATFORM JIG

Unlike AR-15 or AR-10 80% lower specific jigs, the Multi-Platform jigs are able to mill and complete any 80% lower receiver, rather than be limited to one class or platform. The Easy Jig® Gen 3 Multiplatform is able to handle any 80% AR15, AR10, AR9, or AR45 that uses a standard mil-spec trigger pocket, whether forged or billet.

WHY AN 80% ARMS MULTI-PLATFORM JIG?

To put it simply, because we were the very first router-based 80% lower jig, and with all of our time and experience in the market, we remain the best. While other companies were putting out endless copies of the same drill-press jigs that took 6-8 hours to complete, we revolutionized the 80% jig market by turning an everyday router into the most efficient firearms production tool since the CNC machine.

What's more, is we put our money where our mouth is. All of our 80% lower receiver jigs (as well as all of our 80% lowers, our rifle kits, and our 80% pistol products), are guaranteed for life. The best products with the best service. That's why you should choose 80% Arms.
