The 2-7x32mm Burris Handgun scope provides handgun shooters with a wide, flexible range. 2x low end magnification offers quick target acquisition and a very large field-of-view. The 7x zoom at the top provides accuracy at handgun-stretching distances. Posi Lock(TM) is the Burris system that uses a retractable steel post in addition to the normal adjustment springs to firmly lock the turret adjustments exactly how they were set. It provides extra security when firing large caliber handguns with significant recoil.
