The Sig Sauer Tango MSR is one of the new breed 1-10x LPVOs. These scopes blur the lines between an LPVO and what many used to consider “high power” scopes of previous decades. At 10x the Tango actually has a higher magnification than standard issue US military Sniper Rifle optics (granted those scopes have clearer and brighter glass).

The Tango is nicely designed with great care evident in the build and construction. The contact surfaces on its controls are well textured for a firm grip. It features capped turrets that are resettable, though I found the numbers and scale on the dial a bit hard to read precisely from a shooting position. The turrets were loud but not particularly tactile positive.

The magnification ring has a removable throw lever but the design of the grooves and knurling seem to be sufficient to turn the ring without it. The kit comes with an very well designed 34mm offset mount. Sig thoughtfully printed a reference line on the front tube to help the user align the scope to the mount rings.

At low power the scope is truly 1x with no fish-eye distortion. At high power the scope does suffer from drop in brightness and noticeable chromatic aberrations. It typical LPVO distances under 300yrds on man-sized targets will be clear and recognizable despite this.

The MSR reticle looks like a hybrid between an ACSS style horse shoe and a traditional German style T-reticle. It features dots and arrows design to help the shooter lead a moving target. The TANGE features 11 levels of brightness on the horse shoe reticle but it is not noon day sunlight bright.

This scope has a Second Focal Plane (SFP) reticle; the majority of 1-10x LPVOs are First Focal Plane (FFP). A FFP is preferable in long range shooting but on an LPVO with a scale change of 1000% can often make for thin, hard to see center dots at 1x. Because of that, I tend to prefer the simplicity SFP reticles in an LPVO. Testing the scope running multiple target engagement drills at 25yrds, I found it easy to aim and center on my target.

While the TANGO is not the sharpest or brightest glass I’ve seen in a ≥$500 scope, its features, design, and construction certainly makes it feel worth the price.
