Built specifically for hunters in Straight-Wall cartridge states, the VX-Freedom 3-9x40mm Straight-Wall Rifle Scope solves the dramatic bullet drop these cartridges introduce at moderate range. It ships with three pre-calibrated dials, ready for .350 Legend (165gr) right out of the box, with .450 Bushmaster (250gr) and .400 Legend (210gr) dials included, so you can range, dial, hold dead on, and send it. Built around Leupold's Advanced Optical System, this Second Focal Plane scope delivers dependable light transmission and glare reduction in the field. A ZeroStop dial keeps you from cranking past zero by accident, and the lockable eyepiece holds your personal focus setting in place. Like every Leupold Rifle Scope, it's waterproof, fogproof, and shockproof, and it's designed, machined, and assembled in the USA with a lifetime guarantee.
