The SIG Sauer TANGO MSR 3-18X50 is the next evolution of SIG’s tactical riflescope family, delivering serious long-range magnification at a price built for the recreational shooter. This SIG Sauer TANGO MSR pairs a high-performance 6x optical system with low-dispersion glass and an integrated thread-in throw lever for quick magnification changes.

What the SIG Sauer TANGO MSR 3-18X50 is and who it is for

A 3-18×50 lives in the precision and long-range space, with enough low-end magnification for field work and a top end that lets you pick apart distant targets. It is aimed at precision rifle enthusiasts, long-range hunters, and tactical shooters who want real reach and repeatable dialing. The 50mm objective keeps the image bright even at the 18x top end.

This model features a first focal plane reticle with a choice of an illuminated MOA Milling 2.0 or MRAD Milling 2.0 reticle. The SIG Sauer TANGO MSR 3-18X50 delivers dependable waterproof, shockproof, and fog-proof performance for demanding long-range use.

• Integrated thread-in throw lever for fast magnification changes.

Specs and performance woven together

The 6x optical system stretched across a 3-18x range makes this a genuine long-range tool, and the 50mm objective feeds the light needed to keep the picture bright when you reach the top of the magnification band. Low-dispersion glass preserves sharpness and color fidelity, which matters when you are trying to read a small target far downrange.

The first focal plane MOA Milling 2.0 or MRAD Milling 2.0 reticle is the technical centerpiece, keeping subtensions accurate at every magnification so your holdovers and ranging stay true. It offers illumination for low light, and the 1.300-inch Alpha-MSR aluminum cantilever mount comes included. The optic is engineered by SIG Sauer to bring precision features within reach.

Practical use, care, and compatibility

Mount it using the included cantilever mount, setting eye relief on a flat-top rail, leveling the reticle, and torquing to spec. Choose the reticle in your preferred measurement system, then learn its subtensions so you can hold or dial confidently at any distance.

Care is standard for a precision optic: use the flip caps in transit, clean the lenses properly, and rely on the sealed, fog-proof body against the elements. It suits precision rifles, long-range hunting guns, and tactical builds, and you can find compatible mounts and complementary optics in our optics collection.

Precision shooting on a budget is exactly what this scope is built for. The wide magnification span lets you range and read a target at distance, then dial a correction and send it, all with glass and turrets that punch above the price. For a first serious long-range rifle, that combination is tough to beat.

The first focal plane milling reticle keeps your subtensions true at every power, so your holdovers and wind calls stay honest whether you shoot in MOA or mils. With the cantilever mount in the box and a sealed, weatherproof body, it is a ready-made platform for the shooter stepping into distance work. Spend your budget on ammunition and trigger time instead of a pile of accessories, because this scope arrives ready to help you build real long-range skill.
