Handy little tool - Aimpoint Micro/ACRO/Comp/Hunter Tool

Always use the right tool for the job, this does the trick. Throw it in your bag for quick adjustments at the range. More ergonomic than a screwdriver. Bright orange/red color is great for catching your eye should you happen to drop it in the dirt/grass/sand/whatever. Not sure on how they could improve on this handy little tool.
