Sig Sauer Tango MSR 3-18X50mm Rifle Scope Review

My first impression of Sig Sauer Tango MSR 3-18X50mm Rifle Scope

The Sig Sauer Tango MSR 3-18X50mm Rifle Scope promises a lot on paper: first focal plane, illuminated reticle, and a generous magnification range, all wrapped in a package with an included mount at a competitive price. After spending over a decade fine-tuning rifles for everything from precision shooting to close-quarters engagements, I’m always skeptical when I see features typically reserved for high-end optics appearing in more budget-friendly options. Can this Sig Sauer offering truly deliver, or are compromises made that ultimately impact performance?

I was searching for a versatile optic that could transition between mid-range target shooting and longer-range engagements on my precision AR-10 build. Several scopes were in the running, including a Vortex Viper PST Gen II and a Primary Arms GLx, but the Tango MSR’s combination of features and included mount caught my eye. The others would have required purchasing a separate mount, increasing the overall cost.

Upon unboxing, the Sig Sauer Tango MSR has a solid feel; the matte black finish is cleanly applied, and the turrets have a tactile click. The included mount seems sturdy enough, though I immediately noticed it’s a fairly basic design. My initial impression was cautiously optimistic; the scope looked promising, but the proof would be in its performance at the range.

Real-World Testing: Putting Sig Sauer Tango MSR 3-18X50mm Rifle Scope to the Test

First Use Experience

My first outing with the Sig Sauer Tango MSR 3-18X50mm Rifle Scope was at my local shooting range, where I primarily engaged targets at 100 and 300 yards. The weather was clear and sunny, providing ideal conditions for testing the glass clarity and reticle visibility. Mounting the scope was straightforward thanks to the included mount.

Adjusting the turrets to zero the rifle was simple enough, with positive clicks that felt reassuring. However, I immediately noticed that the glass clarity wasn’t quite what I had hoped for, especially at higher magnifications. There was a slight “tunneling” effect at the lowest 3x magnification, and edge distortion became apparent above 12x.

Extended Use & Reliability

After several months of use, including multiple range sessions and a hunting trip in varying weather conditions, the Sig Sauer Tango MSR has held zero consistently. The durability seems acceptable, with no significant signs of wear and tear beyond minor cosmetic scratches. Despite being rained on during my hunting trip, the scope didn’t fog up or experience any water intrusion.

Cleaning the lenses is easy with a standard lens cloth, and the turrets have maintained their tactile feel. However, my initial concerns about glass clarity persist. While the scope is perfectly usable at lower magnifications for close to mid-range shooting, the image quality degrades noticeably as you zoom in, making it less ideal for precise long-range shots. It doesn’t outperform my higher-end optics, but it’s also significantly less expensive.

Breaking Down the Features of Sig Sauer Tango MSR 3-18X50mm Rifle Scope

Specifications

• The Sig Sauer Tango MSR 3-18X50mm Rifle Scope boasts a magnification range of 3-18x, offering versatility for various shooting distances. This range allows for quick target acquisition at lower powers and detailed target observation at higher powers.

• It features a 50mm objective lens, designed to gather ample light for a bright image, even in low-light conditions. A larger objective lens can be crucial for hunting during dawn or dusk.

• The 34mm main tube provides a robust platform for internal adjustments and enhances light transmission. A larger tube diameter often contributes to a wider range of elevation and windage adjustments.

• The illuminated MRAD Milling 2.0 reticle in the first focal plane (FFP) allows for accurate ranging and holdovers at any magnification. The FFP design is essential for maintaining accurate reticle subtensions throughout the magnification range.

• The scope features 0.1 MRAD adjustment increments, enabling precise corrections for bullet drop and windage. Fine adjustments are vital for achieving accuracy at extended ranges.

Performance & Functionality

The Sig Sauer Tango MSR 3-18X50mm Rifle Scope’s primary function is to provide accurate target acquisition and allow for precise shots at varying distances, and it achieves this to a reasonable extent. At lower magnifications, the scope offers a clear and bright image, facilitating quick target acquisition. The higher magnification settings are useful for target identification and observation, although the image quality does degrade noticeably.

The illuminated reticle is effective in low-light conditions, enhancing visibility of the aiming point. However, the illumination is not daylight bright, so it can be difficult to see in bright sunlight. The turrets provide positive and tactile clicks, but the overall feel lacks the precision and refinement of higher-end optics.

Design & Ergonomics

The Sig Sauer Tango MSR has a utilitarian design, with a matte black finish and clearly marked turrets. The included mount is functional and easy to install but lacks any advanced features like quick-detach levers or built-in level. The overall weight is manageable but not particularly lightweight compared to some other scopes in its class.

The eye relief is adequate, and the adjustable diopter allows for a clear image for users with varying eyesight. The magnification ring is stiff but provides enough grip for easy adjustment. While the scope feels solid and well-built, the ergonomics are not exceptional.

Durability & Maintenance

The Sig Sauer Tango MSR 3-18X50mm Rifle Scope appears to be reasonably durable, capable of withstanding normal use and minor impacts. After months of testing, there were no major issues with fogging or water intrusion. The scope is easy to clean and maintain, requiring only occasional wiping of the lenses with a lens cloth.

Proper storage and protection from excessive force are always recommended to prolong the life of any optic. The Sig Sauer warranty provides some peace of mind, but the long-term durability remains to be seen.

Accessories and Customization Options

The Sig Sauer Tango MSR 3-18X50mm Rifle Scope comes with an included mount and flip-up lens covers, providing everything you need to get started. The mount is compatible with standard Picatinny rails, offering flexibility for mounting on various rifles. Beyond that, there aren’t many customization options directly related to the scope itself.

Users can add aftermarket bubble levels, throw levers for the magnification ring, or higher-quality scope rings if they desire. The scope is compatible with standard 34mm scope rings from various manufacturers.
