The FX-II Handgun 4x28mm scope not only eliminates the need to focus on the front sight, but it also eliminates the inaccuracy of a handgun's short sight radius. All that's left is you, the crosshairs, and the game. There's no secret to the enduring popularity of Leupold's fixed power riflescopes. Their simplicity, rugged performance, and supreme accuracy speak volumes. We put nearly a century of optical know-how into each one, for an image that has to be seen to be appreciated. Built around Leupold's Advanced Optical System, the FX-II Handgun offers tried and true light transmission, best in class glare reduction in harsh light, and the resolution and clarity that recreational sportsmen and sportswomen demand.? Tested to the same harsh standards as our other scopes, the FX-II Handgun is 100% waterproof and fogproof. And like all Leupold riflescopes, it's designed, machined, and assembled in the USA and guaranteed to perform for life.
