The glass and reticle draw consistent praise for the price, but budget extra patience, and possibly a torque driver, for the turrets and mount screws.

Overview
The Tango-MSR is a 5-30x56mm first focal plane rifle scope with a 34mm tube, an illuminated MOA Milling 2.0 reticle, and a locking zero-stop elevation dial, sold with a 34mm Alpha-MSR mount and flip-back lens covers.
Positioned as a high-magnification FFP scope below Sig's top-tier lines, aimed at recreational precision shooters rather than competition use. More than one reviewer found the elevation and windage turrets stiff enough to need real effort to adjust, and one had the included mount's screws over-tighten to the point of stripping bits during setup.
- 5-30x56mm first focal plane optics
- 34mm tube with locking zero-stop elevation
- Illuminated MOA Milling 2.0 reticle, 6 brightness levels
- Includes 34mm Alpha-MSR mount and lens covers
Who it's for
Suits shooters who want first focal plane holdover at long range without stepping up to Sig's flagship glass, especially on an AR-platform rifle given the included MSR mount. Less ideal if you need turrets and mount hardware that adjust easily by hand.
Pros and cons
- First focal plane reticle holds true at any magnification
- Lifetime transferable warranty
- Includes mount and flip-back lens covers
- Turrets reported as very tight to adjust
- Mount screws arrived over-tightened, stripping bits for at least one buyer
- Lens flip caps can come loose, though they stay reasonably snug
- Adds noticeable weight with the integrated mount
Performance notes
The 6x zoom system covers 5-30x magnification through a 56mm objective lens with a nitrogen purge for fog resistance and shockproof, waterproof housing. The illuminated FFP reticle holds true at any magnification since it sits in the first focal plane, and the locking zero-stop elevation dial is meant to return to a known zero after dialing for distance, though several owners describe the turrets as stiff to turn.
