The Leupold VX-4HD 4-16x50mm CDS-ZL2 Side Focus Duplex (Model 185456) is a premium, long-range hunting riflescope designed for hunters who need extended magnification and precise target acquisition. Featuring a large 50mm objective lens, a 30mm maintube, and Leupold’s advanced CDS-ZL2 custom dial system, this scope delivers exceptional clarity and performance at longer distances. The non-illuminated Duplex reticle combined with side focus parallax adjustment makes the VX-4HD 4-16x50 an outstanding choice for western hunters, long-range shooters, and anyone who demands a versatile, high-magnification optic with reliable features.

Extended Magnification Range for Long-Range Hunting

With a magnification range of 4-16x, the VX-4HD 4-16x50mm offers significantly more reach than lower-powered scopes. This zoom range provides hunters with the flexibility to engage targets at moderate distances at lower power while offering the precision needed for shots beyond 400 yards at higher magnification. The 4-16x power range makes this scope particularly well-suited for open-country hunting where longer shots are common, such as mule deer, antelope, and elk hunting in the western United States.

50mm Objective Lens for Superior Light Transmission

The 50mm objective lens gathers substantial light, delivering bright and clear images even during the low-light conditions of dawn and dusk. When paired with Leupold’s Twilight Light Management System, this scope maximizes usable light and reduces glare, giving hunters a clear advantage during the critical hours when game is most active. The larger objective also contributes to a wider field of view at lower magnifications, helping hunters locate and track game more effectively.

CDS-ZL2 Custom Dial System with ZeroLock

The CDS-ZL2 turret system allows shooters to install custom elevation dials matched to their specific ammunition, altitude, and environmental conditions. The ZeroLock 2 feature provides a secure push-button lock that prevents accidental dial movement while still allowing fast 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 includes a side focus parallax adjustment, allowing shooters to quickly 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 precision shooting, where even small parallax errors can significantly affect accuracy at extended distances.

Classic Duplex Reticle

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