SIG SAUER TANGO-MSR 1-6x24mm FFP LPVO

SIG SAUER TANGO-MSR 1–6x24mm FFP LPVO

The SIG SAUER TANGO-MSR 1–6x24mm FFP brings a practical low-power variable optic configuration to modern sporting rifles. This exact black model is identified by manufacturer part number SOTM61002 and UPC 798681684519. It combines a 30mm main tube, first-focal-plane illuminated MSR-BDC6 reticle, capped 0.5-MOA adjustments, and an included 1.535-inch ALPHA-MSR cantilever mount.

A true 1x setting supports fast, both-eyes-open shooting at short range, while the 6x maximum magnification provides additional target detail and aiming precision at extended distances. Because the reticle is positioned in the first focal plane, its subtensions remain consistent relative to the target as magnification changes. The BDC6 pattern is therefore useful across the optic’s full power range when the shooter has verified the holds for the rifle, ammunition, and environmental conditions.

Versatile 1–6x Optical Range

The 1–6x magnification range suits rifles expected to move between near and intermediate-distance tasks. At the low end, the wide apparent view and illuminated aiming reference help the shooter acquire targets quickly. Turning the power selector toward 6x increases visual definition for more deliberate shots, target identification, or range work. SIG includes a removable throw lever to make magnification changes easier without adding an aftermarket control.

The MSR-BDC6 reticle provides a central aiming point with additional references intended for holdover and ranging applications. Actual trajectory depends on muzzle velocity, bullet weight, sight height, atmospheric conditions, and zero distance. Confirm every reference at the range rather than treating any ballistic mark as universal.

First-focal-plane construction also changes how the reticle appears. It looks smaller at low magnification and grows as magnification increases, while maintaining the same angular relationship to the target. At 1x, illumination helps draw the eye to the center. At 6x, the enlarged markings are easier to use for deliberate holds. This behavior differs from a second-focal-plane scope, where subtensions are normally accurate at only one specified magnification.

Included Mount and Controls

The supplied ALPHA-MSR cantilever mount creates a ready-to-install package for compatible Picatinny rails. Its 1.535-inch height is well suited to many AR-pattern platforms. The scope uses capped windage and elevation controls to protect the settings during transport and handling, while the 0.5-MOA click value makes zero corrections straightforward.

The illuminated reticle is powered by a CR2032 battery. SIG’s manual specifies alternating illuminated and off positions around the brightness control, allowing the shooter to return quickly to a preferred intensity. A diopter adjustment focuses the reticle for the individual user, and the included lens covers help protect the glass when the rifle is stored or transported.

Setup and Care

Install the optic only on an unloaded firearm. Push the mount forward in the rail slots before tightening and follow the mount manufacturer’s current torque specifications. Set eye relief at the highest magnification from a natural shooting position, then level the reticle before final tightening. Bore-sighting can place the initial zero on paper, but live-fire confirmation is required.

After zeroing, record the confirmed settings and periodically verify that the mount remains secure. If point of impact changes unexpectedly, inspect mount tension, ammunition consistency, and the rifle before readjusting the scope. When illumination is not needed, rotate the control to an adjacent off position to conserve battery life while keeping a preferred brightness level close at hand.

Keep the lenses free of dust and abrasive debris, using clean optical tools rather than ordinary cloth. Check the mount, adjustment caps, illumination, and battery before each important use. This TANGO-MSR package is a strong fit for shooters who want an FFP 1–6x LPVO, useful reticle illumination, and a matched cantilever mount in one factory configuration.
