Description
Once you’ve purchased your SS 80% (G43-compatible) Frame, you’ll need to pair it up with the SS80 Jig and Tool Kit to have all the components and tools required for fabrication and final assembly. This build kit includes the 80% jig for cutting and drilling the frame blank, as well as the parts needed to install your trigger, slide and barrel.
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.
