Overview
The Sig Sauer Tango-MSR 3-18x50mm is a first focal plane rifle scope with a 34mm maintube, an illuminated Milling 2.0 reticle with 6 brightness levels, and a locking zero-stop elevation dial. It ships with a 34mm Alpha-MSR mount and flip-back lens covers.
First focal plane construction means the reticle subtensions hold true at any magnification, which matters for a milling reticle used across a 3-18x range. The locking zero-stop dial targets shooters who dial elevation and need a fast, repeatable return to zero rather than relying on holdover alone.
- 34mm maintube with 6x zoom ratio
- Illuminated Milling 2.0 reticle, 6 brightness levels
- 33 MRAD elevation and windage travel
- Powered by one CR2032 battery
Who it's for
Suits rifle shooters who want a high-magnification FFP optic with click adjustments they can trust to return to zero, on a rifle that takes a 34mm mount. Less suited to shooters who only need a basic duplex reticle at lower power.
Strengths and trade-offs
Drawn from this product's published specifications.
- First focal plane reticle holds true across the full 3-18x range
- Locking zero-stop elevation dial for repeatable returns to zero
- Ships with 34mm mount and flip-back lens covers
- 34mm tube requires checking mount and ring compatibility
- Field of view narrows sharply at 18x (18.3 ft at 100 yards)
- No published buyer reviews yet to confirm long-term durability
Performance notes
The 6x optical system with low dispersion glass covers 3-18x magnification while keeping the illuminated FFP reticle usable at any setting. Total elevation and windage travel run to 33 MRAD each, with 25 MOA per rotation on the elevation dial, and the unit is nitrogen purged for waterproof, fogproof, shockproof use.
