SIG SAUER TANGO-MSR 5-30×56 34mm FFP MRAD Riflescope

SIG SAUER TANGO-MSR 5–30×56 First Focal Plane MRAD Riflescope

The SIG SAUER TANGO-MSR 5–30×56 is a high-magnification riflescope designed for recreational long-range shooting, precision-rifle practice, and target work. It combines a broad 5× to 30× magnification range with a large 56mm objective, a 34mm main tube, a first focal plane reticle, and MRAD-based adjustments. An ALPHA-MSR aluminum mount is included, giving the shooter a coordinated optic-and-mount package for a compatible rifle.

This exact configuration uses SIG SAUER’s illuminated MRAD Milling 2.0 reticle and 0.1 MRAD locking adjustments. The shared MRAD system allows observed impacts, reticle measurements, and turret corrections to be expressed in the same unit. For shooters learning to call corrections or build repeatable range data, that consistency makes the scope easier to use as an integrated sighting system.

5–30× Magnification Range

At the lower end, 5× magnification provides a wider view for locating a target, establishing a stable position, and working at moderate distance. Increasing magnification helps the shooter inspect smaller aiming points, refine hold placement, and see more target detail during longer-range practice. The 30× upper range is especially useful when conditions and target size justify additional visual precision.

More magnification is not always better. Mirage, reduced field of view, brightness, and positional movement become more apparent at higher settings. The wide adjustment range lets the shooter select the magnification that best fits the target, distance, and environmental conditions rather than remaining locked into a single high-power view.

First Focal Plane MRAD Milling Reticle

The illuminated MRAD Milling 2.0 reticle is positioned in the first focal plane, so its apparent size changes with magnification. The reticle’s angular subtensions therefore remain usable throughout the magnification range. A shooter can measure, hold for elevation or wind, and communicate a correction without being limited to one specific power setting.

Illumination helps the reticle remain visible when it would otherwise blend into a dark target or background. It does not replace proper target identification or safe lighting, and the brightness should be set only high enough to provide useful contrast. Excessive illumination can obscure fine reticle detail or draw attention away from the target.

0.1 MRAD Locking Adjustments

The elevation and windage controls use 0.1 MRAD increments. One click represents one tenth of a milliradian, allowing precise corrections that correspond directly with the MRAD reticle. Locking controls help reduce unintended changes during transport, movement, or handling after the rifle has been zeroed.

A durable zero still depends on correct installation. The mount must be secured to a compatible rail, the optic should be leveled, eye relief must be established for the shooter and firing position, and fasteners should be tightened according to the manufacturer’s instructions. After mounting, confirm tracking and zero at the range before relying on the optic.

34mm Tube and 56mm Objective

The 34mm main tube supports the scope’s adjustment system and requires 34mm-compatible mounting hardware. This package includes a 1.420-inch-height MSR mount, which simplifies initial component selection for many modern sporting-rifle setups. Compatibility still depends on the receiver rail, rifle geometry, stock position, and the clearance required around the 56mm objective.

The large objective is intended to gather available light and support a usable image across the magnification range. Image quality in the field will also depend on magnification, focus, atmospheric conditions, and the shooter’s eye position. Correct diopter and parallax setup are important when pursuing consistent precision.

Confirm the Exact Model

This listing is for SIG SAUER manufacturer part number SOTM65001 and UPC 798681696260. It is the 5–30×56 TANGO-MSR model with a 34mm tube, first focal plane illuminated MRAD Milling 2.0 reticle, and MRAD adjustments. It is not the MOA-reticle version or one of the lower-magnification TANGO-MSR configurations.

Before use, read the SIG SAUER instructions, verify all fasteners after initial range sessions, and confirm zero whenever the optic or mount is removed, adjusted, or subjected to a significant impact. Always keep the firearm pointed in a safe direction while installing or checking an optic.
