The Burris C4 Plus riflescopes are designed for the sportsman who wants to maximize his cartridges' ballistic potential. The Cartridge Calibrated Custom Clicker (plus Wind Map) gives hunters the ability to match elevation adjustment to their favorite cartridge - just dial in your range and say goodbye to holdover. Shooters also receive a custom Wind Map to help calculate wind hold-off for their exact ammunition. The uncluttered C4 Wind MOA reticle is easy-to-use working seamlessly with both the custom turret and Wind Map for precise aiming. Surgical accuracy is now well within reach with the C4 Plus system.
