80% Arms 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, they drew on this experience to significantly improve upon the existing polymer jig designs. They 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, 80% Arms decided not to just engineer a better jig, but to over-engineer it. 80% Arms drill guides are designed to provide significantly more support for a drill bit than any other pistol jig on the market today. The GST-9 jig uses a glass filled polymer compound which is 3x stronger than other polymer jigs on the market, meaning you'll never have a drill bit walk, or a flexing jig move your alignment. Instead of simple clasp mechanism, the jig includes five polymer bolts to keep everything tight and in exactly the right place. Why spend the extra time and money to make bolts out of polymer? To eliminate the possibility of over-tightening the jig and destroying it with a standard steel bolt. These polymer bolts will shear when they get to the stress point, and you can safely use the jig with as few as three of them.
The GST-9 isn't just the the most advanced 80% Pistol Frame on the market, it is also 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 ATF regulations, 80% Arms cannot legally include the jig or frame rails with the GST-9 frame. The jig and GST-9 frame must be purchased as two separate items. Each jig includes one set of GST-9 frame rails. You will need one jig for every 80% lower you plan to build. Frame rails are ONLY included with the jig, not with the 80% lower itself.
