The Soule tang sight is the world-wide choice of both target shooters and hunters. High precision Creedmoor sights adjustable for elevation. One full turn of the windage knob changes the left or right aim point by 2.5 minutes of angle (in ½ minute increments). Quick and accurate return to center or previous setting is another big advantage. Ample windage movement for any shooting conditions. Distance between the two mounting holes: 2 3/16” up to 2 5/16” (56 up to 58,2 mm). With 2” (50,8 mm) elevation.
