Tasco BPO 6-24x42mm Mildot Varmint Riflescope Features Adjustable Parallax (10 yds to infinity), Target Knob windage and elevation adjustments with dust covers, and variable power magnification (2.5-10X or 6-24X). The Mil Dot reticle is designed so you can range find distances without taking your eye away from sighting through the scope. Read the dots, know the distance, aim accordingly, and take the shot. If you know your trajectory and distance, you can aim exactly right to hit accurately no matter how far or close your shot is. See our Tasco Mildot Page.
