These thumbscrews are made for quickly taking on and off an ar pistol grip without a screwdriver, mainly intended for the strike industries hammer trigger jig, but it should work with any jig that accepts a2 style grips. The unthreaded version needs to be threaded with a 1/4"-28 die (quit whining, they cost six dollars) OR you can try printing the threaded version if you think your printer is good enough. I also made a version that you can glue a spare grip screw into as long as it has a 1/4" wide socket cap head. Strongly recommend printing these with 3+ walls and high infill. These are intended for TRIGGER/GRIP TESTING ONLY, not real use.
