Clear poly carbonate 1911 barrel bushing wrench for standard 1911A1 barrel bushing manipulation. The see through design allows the user to easily see the position of the bushing detent before the wrench is over rotated causing the detent and spring to fly out and become misplaced (definition: "the dreaded sproing!") This pocket sized tool is a great addition to the 1911 enthusiast that would prefer to have this tool handy at all times and places, it would also make a great key chain fob!
