The Sig Sauer TANGO6 5-30x56mm riflescope is a first focal plane optic built for shooters who demand precision across extreme magnification ranges. Whether you're dialing long-range hunting shots, running precision rifle competitions, or setting up for tactical applications, this 34mm tube scope delivers the optical clarity and mechanical reliability that separate purpose-built glass from the rest. The 5-30x magnification swing handles everything from closer engagements to true distance work, while the 56mm objective gathers serious light for low-light hunts and dawn-to-dusk shooting.
At the heart of the TANGO6 is Sig's HDX optics system—extra-low dispersion and high transmittance glass engineered for maximum light transmission and edge-to-edge clarity. The illuminated DEV-L MOA reticle sits in the first focal plane, meaning it scales with magnification and remains true for holdovers at any power setting. The 7 daylight and 2 night-vision illumination settings let you dial in the perfect brightness for your conditions, and the MOTAC system automatically powers down when stationary to stretch battery life.
Mechanical control comes from the T120 Tactical Turrets—120 clicks per revolution for fine 0.25 MOA adjustments, with 80 MOA of total travel in both elevation and windage. The LockDown Zero System lets you establish a bulletproof zero, lock it down, and reset to it whenever you need. A side focus parallax adjustment keeps images sharp from 100 yards to infinity. Argon-filled internals and IPX-7 waterproofing (full immersion to 1 meter) ensure this scope handles hard use in wet, cold, and dusty conditions. The package includes a custom-lasered SBT elevation dial calibrated to your specific ballistics—a serious advantage for long-range shooting right out of the box.
The integrated LevelPlex Digital Anti-Cant System detects reticle tilt with user-selectable +/-0.5° or +/-1.0° sensitivity, a feature that catches mistakes before they cost you a shot. At 42 ounces, it's substantial glass built to sit still.

Frequently Asked Questions
What's the difference between the TANGO6 5-30x56 and other long-range scopes in this magnification class?
The TANGO6 combines a robust first focal plane reticle with extremely precise turret control (0.25 MOA clicks, 120 per rotation) and mechanical features like the LockDown Zero System and digital anti-cant detection. It's built for serious distance shooters who need confidence in repeatability and the ability to shoot holdovers accurately at any magnification. The included custom-lasered SBT elevation dial is a significant practical advantage that many competitors don't bundle standard.
Is the TANGO6 suitable for AR-15 and bolt-action rifle platforms?
Yes. The scope is designed for both MSR/AR and bolt-action platforms. The 34mm tube and standard MOA adjustment increments make it compatible with a wide range of modern rifle setups, provided your rifle's mounting system accepts 34mm rings.
What does the side focus do, and when would I use it?
The side focus parallax adjustment allows you to eliminate parallax error—the optical illusion where the reticle appears to shift position if your eye moves slightly. It's set at 100 yards; once you adjust for your shooting distance, the image stays sharp and the reticle position remains true, even if your cheek position shifts slightly. Essential for precision shooting.
How does MOTAC (Motion Activated Illumination) work?
MOTAC automatically powers the illumination on when it detects motion and shuts it off when the scope remains still. This extends battery life significantly since the illumination isn't constantly running. It's a practical feature for hunters and field shooters who want a ready illuminated reticle without worrying about draining the battery between use.
