WHAT IS A PISTOL 80 LOWER JIG?

To put it simply, an 80% pistol jig helps you complete an 80% Glock compatible pistol, and turn it into a working firearm. Our jig is the most secure platform on the market and for good reason. Other companies opt for a plastic clasp to sandwich an 80% pistol frame between the jig’s two halves. We choose to use 5 steel bolts instead to make the process a guaranteed success.

The 80 Percent Arms 80% Pistol Jig was uniquely designed for building our GST-9 Pistol Frame, which is the first modular 80% Glock-compatible frame.

WHY CHOOSE OUR JIG?

If you are buying a GST-9 Pistol Frame you will require our pistol 80 lower jig to complete your build. The GST-9 is only compatible with 80 Percent Arms pistol 80 lower jig. Not only do you need the jig to drill the cire-control group pin-holes, but their internal rails of the frame are also included with the jig package. Don’t forget to pick one up for every frame or build kit you purchase!
