This Glock Auto Sear Class 2 Jig enables a FFL/SOT to complete our FatBack into a NFA registered machinegun.  The jig enables you to properly complete the 80% Glock FatBack backplate in two simple steps utilizing a drill press and an X,Y vice (can be purchased from Harbor Freight). The Jig is manufactured from solid 17-4 Stainless Steel which will last for many builds. You will be required to drill the hole for the selector pin and mill the slot in the back of the backplate for the disconnector. The Jig simplifies this process.  The FatBack sear is not included; see separate listing. 

This Jig is intended for a SOT manufacture to complete a Post-Sample Machinegun. You must file a Form 2 in accordance with Public Law 99-308.   Shipping will commence approximately November 24, 2024.

All NFA Rules apply.
