Sig Sauer Electro-Optics Sotmc11000 Tango-Msr Black 1-10X 24Mm

The Sig Sauer Tango-MSR is a 1-10x24mm low-power variable optic built for shooters who want versatility without complexity. This LPVO bridges the gap between close-quarters speed and mid-range precision, making it equally at home on a carbine used for home defense, competition, or general duty work. The scope comes factory-mounted on Sig's compact MSR cantilever mount—no gunsmith visit or additional hardware needed—and ships pre-leveled and ready to shoot. That means less time tinkering and more time training.

The optical design prioritizes what actually matters in real-world use: sharp, edge-to-edge clarity and strong low-light performance, even at lower magnification where edge definition is hardest to nail. The illuminated MSR BDC-10 reticle adapts to changing light conditions, with six brightness settings and a positive off detent between each step—no guessing whether you've dialed the light up or down. Metal turrets replace plastic where it counts, delivering the durability and confidence you expect from a fighting optic. A 30mm tube, >80 MOA of elevation and windage travel, and a consistent 30 MOA per rotation give you room to work at distance or dial for specialty loads. The included flip-back lens covers and removable throw lever round out a package designed for serious use.

Waterproof, shockproof, and fog-proof construction means the Tango-MSR stays reliable whether you're running a timed course of fire, hunting in wet conditions, or deploying it in less predictable environments. At 26.5 ounces with the mount, it's light enough not to throw off your handling or fatigue your shooter during longer sessions. Second focal plane placement means hold-overs work true only at 10x, which is the smart trade-off for an optic this flexible.

Specifications

Frequently Asked Questions

What firearm platforms is the Sig Tango-MSR compatible with?

The Tango-MSR ships on Sig's compact MSR cantilever mount, which is designed to interface with Sig's MSR platform rifles. The included mount is factory-installed and pre-leveled. For compatibility with other platform-specific rails or mounts, contact Sig Sauer directly or consult your rifle's manual.

Is the optic ready to use right out of the box?

Yes. The Tango-MSR comes factory-mounted on the compact MSR cantilever mount and pre-leveled from the factory. You can attach it to a compatible rifle and begin shooting without additional setup. Lay-flat lens covers and a removable throw lever are included.

What battery does this optic use, and how long does it last?

The Tango-MSR uses one CR2032 battery to power the illuminated reticle. Battery life specifications are not provided; Sig Sauer is the best source for expected runtime under normal use.

What is the difference between first and second focal plane, and why does this scope use second focal plane?

The Tango-MSR is second focal plane, which means the reticle size remains constant throughout the magnification range, but BDC hold-overs are accurate only when the scope is dialed to 10x magnification. This design is common in LPVOs because it keeps the reticle usable and easy to see at low power, where most shooters spend their time in fast-moving scenarios.
