GLOCK® Compatible 80% Frame Jig

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.
