This complete 3D printer-made jig assembly is designed specifically for AR 15 mil. spec. receivers for use to convert to select-fire by Type 07 FFL’s/Class 2 SOT’s.

This unit accurately locates (held within .001”) the 2 autosear drilling holes as well as depicts not only the shape but also the depth specifics of the select-fire control pocket layout.

The entire completion process may be done with only a drill press and Dremel tool for those who do not have access to a milling machine.
