The Warren® Blacked Out Rear Sight and the CANiK® White Dot Front Sight Set ensures that the shooter is perfectly engaged to the target. This sight system is the preferred option for less than ideal lighting conditions. The black out rear sight features a unique wave design that features concave corners for an extra wide field-of-view. The U-Shaped notch has slightly rounded corners to prevent clothes snagging when drawing, and direct the eye quickly to the front sight.
