Crimson Trace’s Hardline 4-16x42mm Riflescope was designed with tactical and competition applications in mind, and comes packed with user-friendly features. It features exposed, spring-loaded turrets for making adjustments to windage and elevation in the field, and the zero-reset feature allows the user to instantly dial back to their original zeroing. The Hardline 4-16x42mm is also equipped with the CT Custom BDC Long Range Reticle, which has been optimized for extreme accuracy at long range and has a multitude of holdover points to compensate for bullet drop. This reticle is also compatible with Crimson Trace’s exclusive Trace Ballistics Calculator, which takes the guesswork out of compensating for bullet drop by taking into account variables such as load data, magnification, and weapon type to determine the exact holdover point. In addition, the Hardline scopes are given MOC (Maximum Optical Clarity) lens coatings for sharper, glare-free images.
