Jig design runs in our blood. We invented the router based jig and pioneered every major breakthrough in jig design for the AR platform. When it came to designing a jig for the GST-9, we drew on this experience to significantly improve upon the existing polymer jig designs. We found that one of the most common complaints about existing polymer pistol frames centered around issues with the jigs. They tend to be flimsy, they are not held together securely, and the drill guides are too short and weak, which results in many people accidentally ruining their lowers.

To solve this, we decided not to just engineer a better jig, but to over-engineer the hell out of it. We use premium USA glass-filled polymer resins to make our jigs, and our drill guides are designed to provide significantly more support for a drill bit than any other pistol jig on the market today. Instead of a simple clasp mechanism, we include five steel bolts to keep everything tight and in exactly the right place, meaning you'll never have a drill bit walk, or a flexing jig move your alignment.

We haven't just made the most advanced 80% Pistol Frame on the market, we've made sure completing it is foolproof. The GST-9 jig is so simple, you can complete your frame in minutes, with the best results in an 80% yet.

Every jig comes with a set of frame rails, all the tools you will need to complete a frame at home, and a detailed instruction manual to walk you through the simple process.

Due to recently changed ATF regulations, we cannot legally include the jig or frame rails with the GST-9 frame. The jig and GST-9 frame must be purchased on our website as two separate items. Each jig includes one set of GST-9 frame rails. You will need one jig for each 80% lower you plan to build. Frame rails are ONLY included with the jig, not with the 80% lower itself.

How easy is it to build? Check out the instruction manual and see for yourself!
