GLOCK® Compatible 80% Frame Jig
GLOCK®-compatible 80% frames provide the same size, specifications, and dimensions as a factory GLOCK® pistol frame. Requiring minor fabrication with some hand tools to make it ready for assembly, the 80% frame is not legally considered a firearm under federal law. The listed jigs provide the tools and templates required for cutting and drilling the frame, allowing you to install factory or aftermarket GLOCK® components -- a barrel, slide, sights, trigger and parts kits -- to complete your build.
How The Frame and Jig Works
Until your 80% frame is fabricated (cut and drilled for assembly) it isn't legally considered a firearm. Your frame and jig ships to your front door together, just like any other online purchase. Once received, you'll use the jig to fabricate the frame. A set of drill bits and end mill bits are provided to complete all necessary steps. The jig works by securing the frame and illustrating where and how to cut and drill. Easy-to-follow instructions guide you along the way, and no experience or familiarity with firearm frames or the GLOCK® platform is required!
The following tools are require:
- Handheld drill
- Bench-top vise
- Dremel, snips, or files
- *Drill press (optional)
*The frame can be easily cut and finished with snips, and flat and round hand files, though each kit includes an HSS end mill. Unlike aluminum 80% lowers, you can safely cut the polymer 80% frame by gently milling with a drill press and the end mill.

Not a Handgun Under Federal Law
These un-finished 80% pistol frames are not considered handguns or firearms under federal law, nor does the ATF consider them firearms. Because they are not functional, they can be shipped like any other product to most states. They do not require an FFL, background check, transfer fee, or other special taxes or paperwork.
State Laws May Vary
Contrary to federal law, some states have either restricted or banned the sale, transfer, and ownership of 80% lowers, firearm blanks, and other gun parts. Because of these restrictions, we cannot ship our products to certain states. Please confirm whether your state is restricted on our Shipping & Return Policy before placing an order. We cannot fulfill orders to restricted states if placed.
