Designed to be the best Low Power Variable Optic (LPVO) in its price range, the SIG SAUERA(R) TANGO-MSR combines a high-performance 10x optical system with an illuminated, first focal plane bullet drop reticle to give you all the tools you need to engage targets at medium and close range. The low-dispersion glass is much better and clearer than anything else in its price range, providing you with picture-perfect clarity and contrast across the entire field of view. The BDC10 reticle features a wealth of indicator markings to help you determine windage and elevation holds, and because it's on the first focal plane, it works across the magnification range. Finished off with incredibly robust 100% waterproof, fogproof and shockproof construction along with SIG's Infinite Guarantee, it's everything you want in a Tactical Scope at a price that makes sense.
