The Fix It Sticks Aimpoint Bit is a custom bit designed to aid in the adjustment of Aimpoint Sights. The two prong design specifically works with the windage and elevation adjustment knobs. Features semi-circular wings designed to fit "coin-slot" style adjustment knobs / battery covers and the molded synthetic polymer won't mar or scratch the finish of the sight. The bit has a metal A 1/4" Hex Base which allows it to work with any A 1/4" driver.NoteIntegrates perfectly with Fix It Sticks Replaceable Edition and T-Way Wrench for field / travel use.
