The Leupold VX-4HD 3-12x50mm CDS-ZL2 Side Focus Duplex (Model 185454) is a premium, high-performance riflescope designed for hunters who need maximum light transmission and precise long-range capability. Featuring a large 50mm objective lens, a 30mm maintube, and Leupold’s advanced CDS-ZL2 custom dial system, this scope delivers exceptional clarity and brightness in low-light conditions. The non-illuminated Duplex reticle combined with side focus parallax adjustment makes this model an outstanding choice for serious hunters who want a simple, reliable, and highly capable optic for a wide range of hunting scenarios.

Enhanced Low-Light Performance with 50mm Objective

The 50mm objective lens on the VX-4HD 3-12x50mm gathers significantly more light than smaller objectives, providing a brighter and clearer image during the critical low-light periods of dawn and dusk. This makes the scope particularly effective for hunters pursuing game in timber, mountainous terrain, or during early morning and late evening hunts. Leupold’s Twilight Light Management System further enhances performance by maximizing usable light and reducing glare, giving hunters a clear advantage when visibility is limited.

CDS-ZL2 Custom Dial System with ZeroLock

The CDS-ZL2 turret system allows shooters to install custom elevation dials matched to their specific ammunition and environmental conditions. The ZeroLock 2 feature provides a secure push-button lock that prevents accidental movement of the elevation dial while still allowing quick and easy adjustments when needed. Once zeroed, the turret locks firmly in place, giving hunters confidence that their point of impact will remain consistent even during rough handling in the field. This system offers the convenience of dialing for distance with the security of a true zero lock.

Side Focus Parallax Adjustment

This model features a side focus parallax adjustment, allowing shooters to quickly and easily eliminate parallax error from any shooting position. The side focus knob is conveniently located on the left side of the scope, making it easy to reach without breaking shooting position. This feature is especially valuable for long-range shooting and precision hunting, where even small parallax errors can affect accuracy at extended distances.

Classic Duplex Reticle

The non-illuminated Duplex reticle is one of the most trusted and widely used reticles in the hunting world. Its bold outer posts quickly draw the eye to the center, while the finer inner crosshairs allow for precise shot placement. Because it is located in the second focal plane, the reticle remains a consistent size throughout the magnification range, making it fast and intuitive for hunters who prefer a simple, uncluttered aiming point that performs well in a variety of lighting conditions.

30mm Maintube and Rugged Construction

The VX-4HD 3-12x50mm is built on a strong 30mm maintube, which provides greater durability and a wider range of windage and elevation adjustment compared to 1-inch tubes. The scope is machined from aircraft-grade aluminum and is fully waterproof, fogproof, and shockproof. Leupold’s legendary build quality ensures this optic will withstand heavy recoil, harsh weather, and the demands of backcountry hunting for years to come.
