Every jig we produce has led the market. This isn’t hyperbole, this isn’t fluff, it’s just the truth. From the invention of the original AR-15 router jig, to the re-imagination of 80% Glock compatible jigs, we pride ourselves on having the easiest, most accurate, and most durable jigs available for home-building enthusiasts.
The MOD1 Jig is no exception. Taking the already rock-solid jig for the original GST-9, we’ve improved on the finishing process even further. Extended drill guides offer more support for the drill bits allowing more precise completion, helping eliminate the most common mistake when building 80% pistols: drilling oblong or off center holes.
We’ve also added an additional bolt point, making sure that the jig has 100% coverage in its clamping system. This ensures that every cut you make is in the right place, every time. The MOD1 Jig is also made of glass-filled reinforced polymer, a compound 3x stronger and more rigid than competing 80% glock compatible jigs on the market.
The MOD1 jig is so simple, you can complete your frame in minutes, with the best results in an 80% yet. In fact, we would call it damn near foolproof. How easy is it to build? Check out the instruction manual and see for yourself!
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.
JIGS ARE AVAILABLE FOR SALE ONLY TO CUSTOMERS WHO HAVE PURCHASED A FRAME. LIMIT OF 1 JIG PER FRAME.
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.
Shipping Restrictions: This item is restricted from shipping to New Jersey, Hawaii, Connecticut, Rhode Island, Washington D.C., and San Diego City.
Because the GST-9 is not a firearm, in most cases, it is currently legal to purchase and own an unfinished frame in California. California law prohibits building an off-roster handgun as well as a homebuilt firearm that does not contain an integral 3.7 oz piece of stainless steel. If you are purchasing a GST-9 that ships to California, you certify that you have a law-enforcement exemption, or intend to build and maintain the product outside of the state.
