Rifle owners must have!!! - Wheeler Fat Torque Wrench Screwdriver with 10 Bit Set

Very useful and very durable. Comes with the most commonly used bits but it works with all of the ones you might already have. Very easy to adjust and light enough for me to carry around in my small tool pouch. Absolute must have for scope installation. No reason not to have one in your toolbox if you own a long gun...
