SS80 Builder Tool Set and Jig



Ready to assemble your G43-compatible pistol? First you need to pick up the SS80 Jig and Tool Kit. This kit is the critical other half to your build project: It includes the tools and jig necessary for cutting and drilling the frame, as well as the components you’ll need to install to make it ready for final assembly. Rest easy -- no experience is required and the whole process of machining takes less than two hours with simple tools!

Easy-to-Follow Instructions

No experience is required to cut and drill your 80% frame! The jig includes easy-to-follow video instructions available online. Fabricating the frame requires basic hand tools, like a bench-top vise, handheld drill, Dremel, and some hand files or sandpaper for final fitment.

Please note: The locking block for this item used to require the builder to drill the holes for the locking block pin his/herself. However, this step is no longer necessary, as the locking block for this item now comes with its pin holes pre-drilled. When referencing the accompanying instructional video, this step may be skipped.

What’s Included

  • (1) SS80 80% Frame Jig & Screws
  • (1) Pre-Drilled Locking Block
  • (1) Trigger Housing Pin
  • (1) Rear Rail System
  • (1) Set of Drill Bits

Important Information

Due to ATF policy, the SS80 Jig and Tool Kit must be bought and shipped separate from the SS80 80% Frame. Neither component is considered a firearm under ATF determinations and federal law. The ATF Determination Letter is available here.
