VictOptics SOI Series — Your First MPVO for Airguns

VictOptics’s new SOI MPVO series is here — a complete lineup of scopes created specifically for airguns. The SOI MPVO series offers a more budget-friendly option compared to our popular S6 LPVO line, while still delivering the same dependable quality and premium lens performance you expect from VictOptics.

The blog is organized around five key aspects — from shooting scenarios and compatible airgun types, to the benefits of a 1-inch tube, SOI’s innovative reticle design, and a full overview of the SOI MPVO lineup. Now, let's dive in and take a closer look.

1. SOI MPVO Series Airgun Scopes Introduction: From VIOC-01 to VIOC-06

Here are a complete lineup of SOI MPVO series airgun scope:

• VictOptics SOI 1.5-5×20 MPVO Airgun Scope (VIOC-01)

• VictOptics SOI 2-7×32 MPVO Airgun Scope (VIOC-02)

• VictOptics SOI 3-9×40 MPVO Airgun Scope (VIOC-03)

• VictOptics SOI 4-12×40 MPVO Airgun Scope (VIOC-04)

• VictOptics SOI 3-9×40 MPVO Airgun Scope AO (VIOC-05)

• VictOptics SOI 4-12×40 MPVO Airgun Scope AO (VIOC-06)

The parameter chart of SOI MPVO series airgun scopes is as follows:

As shown in the chart, the VIOC-01 and VIOC-02 scopes have a fixed parallax setting at 50 yards, while the VIOC-03 and VIOC-04 are set at 100 yards. The VIOC-05 and VIOC-06 feature an AO (Adjustable Objective) parallax, allowing you to adjust the parallax for close-range distances. This AO feature ensures a crisp focus at shorter ranges, such as 5m or 10m, making these scopes more versatile and suitable for a variety of shooting scenarios. Learn more about AO parallax setting in this blog.

Whether you're an airgun shooter looking for a reliable MPVO or a firearm enthusiast seeking a high-performance scope, VictOptics SOI series offer excellent choices. The SOI scopes provide an affordable, lightweight solution for airsoft and airgun applications. For high-end MPVO, check our another blog post.

2. Best-Suited Shooting Scenarios for the SOI MPVO Series

The SOI MPVO series scopes are able to use both in airgun hunting and recreational shooting like plinking and target shooting. 

For airgun hunting, we are actually talking about small game hunting, varmint hunting or pest control. These scenarios often involve fast, reactive shooting, so having a scope with a forgiving eyebox is key to getting a full field of view quickly. Weight is another important consideration—many hunters choose compact airguns for better mobility, and a compact scope naturally becomes the ideal match. With their wide field of view and generous eyebox, the SOI series airgun scopes make rapid target acquisition smooth and effortless.

When it comes to target shooting, your choice of magnification should depend on the shooting distance.

● For shooting distances up to 35 yards, a VictOptics SOI 4-12x40 MPVO (VIOC-04) scope is a solid option for your airgun.

● For 5-50m target shooting, the VictOptics SOI 1.5-5x20 MPVO (VIOC-01) and VictOptics SOI 2-7×32 MPVO (VIOC-02) is ideal.

● For distances between 20-200m, the VictOptics SOI 3-9x40 MPVO (VIOC-03) provides optimal magnification and clarity.

● For versatile close and mid-range shooting, we have VictOptics SOI 3-9x40 MPVO AO (VIOC-05) and VictOptics SOI 4-12x40 MPVO AO (VIOC-06) with AO adjustment.

3. Compatible Airgun Types for SOI MPVO Scopes

All SOI scopes are airgun-rated, making them suitable for spring-piston air rifles especially break barrel air rifles. If you want to learn more about airgun basics, go check this blog.

For example, both the HW99S (99 S), an entry-level spring-piston air rifle, and theGamo Whisper Wildcat .22, a break barrel action rifle, are perfect for small game hunting, pest control, or informal plinking. To engage small game at 20-25 meters with the 99 S, we recommend using a 3-9x AO scope for optimal performance.

While for heavy-recoil spring-piston air rifles, consider the shockproof ability first. To mount on a spring-piston air rifle, a scope should remain stable and reliable. Otherwise, the internal parts may loosen after just a few shots.

The SOI scopes feature a robust aluminum alloy monotube design, ensuring they remain secure and won’t break apart, even under heavy recoil.

4. Why 1-inch Tube Scope? Understanding Its Compact Design

Except for the VIOC-06 SOI 4-12x40 AO, all scopes in the SOI series feature a 25.4mm / 1 Inch diameter tube. The small tube diameter realizes compact and lightweight design. The 6 models of air gun scope weight range from 200 to 600 grams, offering the lightest possible options for your airgun configuration.

Let's compare the weight & size between SOI & S6/S4 Series.

VIOC-01 (1.5-5x) VS S6 LPVO (1-6x)

SOI VIOC-05 (3-9x) VS S4 OPSL16 (4-16x)

The VIOC-05 features a 24.5mm diameter tube, while the OPSL16 has a 30mm tube. Both scopes offer 1/10 MIL click adjustments, a similar weight, and a comparable field of view (FOV).

It’s a popular choice for those who regard weight as a priority by reducing overall weight of air gun setup. Moreover, 1-inch tube scope is cheaper than 30 and 34mm tube due to the low manufacturing cost. That’s why makes it the most budget entry-level scope to choose.

Normally, 1-inch tube scopes offer a smaller windage and elevation adjustment range than 30mm tube diameter. Therefore, they are often seen in low magnification scopes for close to medium-range shooting. If you want to learn more about tube size, go check this blog.

5. Innovative Reticle Design for Enhanced Targeting

As for reticle patterns, SOI MPVO series scopes are equipped with VNM-1 MIL which is designed for multi-scenario accurate adjustments. The dash on the reticle can help you with windage and elevation adjustments. At the same time, we built them with red & green dual illumination settings. You can see the reticle clearly under low-light conditions and different shooting backgrounds, versatile and reliable for various shooting scenarios.
