The Master Sight Pusher is a professional grade tool that makes quick work of changing pistol sights while protecting both gun slides and the sights themselves. Heavy-duty, built to last and smartly designed to work on almost all modern pistol sights. The over-sized, ergonomic Easy Torque Handle partners with extra fine drive threads to provide maximum torque with minimal effort when removing or installing sights. The Universal Press Block features multiple contact surfaces for almost any size and style of press-fit dovetail slots and sight profiles. Adjustable non-marring contact surfaces securely hold both 1911 and flat bottom pistol slide styles. Mfg: Real Avid
