Victoptics S4 6-24×50 FFP Rifle Scope OPFF-02

The Victoptics S4 6-24×50 FFP Scope is designed for air guns, .22 LR rimfire rifles, benchrest shooting and hunting. With 6-24x magnification and a 50mm objective lens, it provides flexible magnification for detailed target viewing. In addition, its fully multi-coated optics help deliver a clear image from edge to edge.

The scope features a VIS-FMIL etched-glass reticle designed to support aiming and ranging references. Furthermore, its first focal plane (FFP) design means the reticle scales with magnification, so its sub tensions remain consistent across the zoom range.

The 30mm monotube provides a solid base for the adjustment system. Meanwhile, the 1/10 MIL click value allows for fine adjustments, and the turret lock helps prevent accidental changes. The side-focus system adjusts from 20 yards to infinity, while the long 96mm eye relief allows flexible eye positioning.

 

6-24x Magnification and Clear Optics

The Victoptics S4 offers a 6-24x magnification range. At lower magnification, you get a wider field of view. However, at higher magnification, you can view smaller targets in greater detail.

The 50mm objective lens works with fully multi-coated optics to help improve light transmission. As a result, the scope supports a clear sight picture across its magnification range.

At 100 yards, the field of view ranges from 21.2 feet at 6x to 5.3 feet at 24x. Therefore, you can see a wider area at lower power, while higher magnification gives you a closer view of the target.

 

First Focal Plane VIS-FMIL Reticle

The Victoptics S4 6-24×50 FFP Scope features a VIS-FMIL etched-glass reticle. Its reticle design provides aiming references and is intended to support ranging.

Because this is a first focal plane scope, the reticle changes apparent size as you adjust magnification. This means its sub tensions remain consistent throughout the zoom range, which can help when using reticle references at different power settings.

The reticle is not illuminated. However, its etched-glass design provides a reticle without the need for a battery-powered illumination system.

 

Fine MIL Adjustments and Turret Lock

The scope features 1/10 MIL adjustment clicks, with a stated elevation adjustment range of 13 MIL and a windage adjustment range of 13 MIL.

In addition, the turret lock helps prevent unwanted changes to your settings. Pull the turret up to adjust it, then press it down to lock it in place. This design helps keep your settings secure during handling and transport.

 

Side Focus from 20 Yards to Infinity

The side-focus system adjusts from 20 yards to infinity. Therefore, you can bring targets at different distances into focus.

The side-focus knob includes markings for 20, 25, 50, 75, 100, 200, 400 and 600 yards, as well as infinity. Meanwhile, the fast-focus eyepiece offers diopter compensation from -2 to +2, allowing you to adjust the reticle focus to suit your eyesight.

The included power ring lever also makes it easier to change magnification when needed.

Long Eye Relief and Durable Construction

The Victoptics S4 provides 96mm (3.8 inches) of eye relief, giving you more room to position your eye behind the scope.

Its 30mm monotube is made from 6061-T6 aircraft-grade aluminium and features a matte black finish. Furthermore, the scope is nitrogen purged to help prevent internal fogging. It is also water resistant and has been shock tested to 750 G.

The included 3-inch sunshade helps reduce glare and reflections entering the objective lens. In addition, the flip-up lens caps help protect the optics from dust and scratches when the scope is not in use.
