The Sig Sauer Tango-MSR 1-6x24mm LPVO (low-power variable optic) is a second focal plane scope built for shooters who need versatility across multiple distances without sacrificing clarity or speed. Whether you're running a modern rifle on the range, in competition, or hunting mid-range game, this scope delivers a wide field of view at 1x for quick target acquisition and enough magnification at 6x to place precise shots downrange. The illuminated red BDC6 reticle offers multiple brightness levels to suit any lighting condition, and the integrated throw lever makes magnification changes fast and intuitive—critical when your shot opportunity doesn't wait.
Built to Sig's tactical standards, the Tango-MSR is sealed against the elements with waterproof, shockproof, and fog-proof construction. The 30mm maintube provides robust adjustment range: 100 MOA of elevation and windage travel with 44 MOA per rotation, giving you room to dial for distance or compensate for wind without running out of adjustment. The ALPHA-MSR cantilever mount is included and ready to go—one less decision to make when you're building your rifle.
At 18.5 ounces, it's light enough for a hunting rifle or duty gun yet substantial enough to feel solid in hand. The eye relief stays consistent across the magnification range (3.93" at 1x, 3.74" at 6x), and the diopter adjustment (±2.5) lets you dial in a sharp sight picture regardless of your eyesight. Lay-flat flip-back lens covers protect the glass when it matters.

The 1-6x range covers both. At 1x, you get a 124.8-foot field of view at 100 yards—ideal for quick target acquisition in brush or on the move. At 6x, you can place precision shots at mid to extended range without needing a higher-magnification scope that eats up your field of view. The integrated throw lever lets you shift between powers fast.
Yes. The ALPHA-MSR cantilever mount is included, so you can mount the scope to your rifle immediately without a separate purchase.
In a second focal plane scope, the reticle stays the same size no matter what magnification you choose—only the target gets bigger or smaller. This means you use your reticle holdovers accurately only at the designed magnification (typically 6x on this scope); at lower powers, holdovers won't track as precisely. For a 1-6x LPVO used mostly at 1x for quick shots and 6x for dialed adjustments, SFP is a solid choice and helps keep the optic compact and lightweight.
Yes. The illuminated red BDC6 reticle has 11 brightness levels, so you can adjust for dawn, dusk, or indoor/low-light shooting. The 24mm objective and 1x magnification also preserve light transmission and field of view when brightness is limited.
