A sight apparatus for a shotgun includes a lens movable longitudinally and laterally with respect to the axis of the barrel so that the entire shot pattern at a given target distance for a given barrel choke is visible to the shooting eye of the shooter through the lens in a properly calibrated sight. The lens is colored so that a colored pattern indicative of the shot pattern is superimposed over a target at the given target distance. The mechanism providing for longitudinal and lateral adjustment of the lens relative to the axis of the barrel includes a longitudinally extending track pivotally mounted to the barrel adjacent the muzzle end. The track is formed to include a plurality of lateral slots within which tab extending from a frame holding the lens is received.
