SwampFox ARH16241-B: The Swampfox Arrowhead LPVO series meets or exceeds every requirement for serious law enforcement and self-defense applications. Locking turrets require no tools to prevent unintentional adjustments. Arrowhead's state-of-the-art optical design creates a brighter sight picture, a wider field of view, and excellent resolution. Second Focal Plane construction provides a consistent reticle size at all magnifications. The result is an instant, familiar sight picture for unbeatable speed when it counts most; from close quarters distance out to 200 yards. You need to be at maximum magnification to use the medium-range holdovers, so Arrowhead\'s included throw lever lets you slap your magnification to the max in a heartbeat. Arrowhead\'s lever attaches directly via four bolts-there\'s no ring to slip or loosen over time. Arrowhead features push-pull locking turrets that require no tools and can be quickly used out in the field. Push the turrets towards the scope body to lock them in place. Pull them away from the scope body to adjust. Real simple, real tough. No more worries that a turret got \"bumped\" away from its zero when you weren\'t looking. MOA reticles are paired with 0.5 MOA-per-click turrets. MIL reticles are paired with 0.1 MIL-per-click turrets. Arrowhead features dual LED emitters, making daylight bright etched reticle illumination possible at the highest settings. For those who must press on in the darkest night, the first two brightness settings are night-vision compatible and cannot easily be seen by the naked eye at all. Arrowhead\'s illumination knob features a tactile \"OFF\" notch between each of the 12 brightness settings.
