SIG TANGO 6T DVO 1-6X24 Riflescope

The SIG TANGO 6T DVO 1-6×24 riflescope is the latest variant of a low power variable optic that has already proven itself, and it arrives equipped with a Hellfire DWLR-556 illuminated reticle. It is designed for MSR and AR platforms as well as bolt action rifles, which makes it one of the more versatile 1-6x options on the market. It also ships free.

Low power variable optics have taken over for a reason. At 1x they behave like a red dot, and at 6x they let you identify and engage at distances a dot cannot manage.

What the SIG TANGO 6T DVO Package Includes

The optic sports SIG’s HDX Optics and offers industry leading light transmission and optical clarity, which is what you are paying for in a scope of this class. Glass quality is the difference between seeing a target and identifying it, particularly at the edges of legal light. The Hellfire DWLR-556 illuminated reticle is designed around the ballistics of common 5.56 loads.

Also included is the ALPHA4 Cantilever Mount, which until now was unavailable on the commercial market and is widely fielded by the US Department of Defense. That single inclusion removes a significant separate purchase and guarantees the mount and optic were designed to work together. The package also adds magnetically retained lay flat flip back caps.

Key Features

• Hellfire DWLR-556 illuminated reticle with night vision compatible illumination settings and a locking illumination dial.
• HDX Optics delivering industry leading light transmission and optical clarity across the magnification range.
• ALPHA4 Cantilever Mount included, a mount widely fielded by the US Department of Defense.
• IPX-8 rating providing protection against complete water immersion at 20 meters, plus fog proofing.
• Magnetically retained, lay flat flip back lens caps that stay out of the way when open.
• Power selector ring throw lever included for fast magnification changes under time pressure.

Optical and Mechanical Specifications

The 1-6×24 configuration is the practical heart of the optic. True 1x lets you shoot with both eyes open at close range, and 6x provides enough magnification to identify targets and make precise shots well beyond what a red dot allows. The 24mm objective keeps the package compact and light on the rifle, which is exactly right for an MSR or AR build.

Durability specifications are just as important on a fighting optic. The SIG TANGO 6T DVO carries an IPX-8 rating for protection against complete water immersion at 20 meters, and it is fog proofed so internal condensation does not blind you when the temperature swings. The locking illumination dial prevents accidental setting changes, and the throw lever means magnification changes happen by feel. SIG Sauer covers each optic with its warranty program.

Mounting, Zeroing, and Maintenance

Use the included ALPHA4 Cantilever Mount and set it up properly. Position the SIG TANGO 6T DVO so you get a full, clear sight picture at 6x from your natural shooting position, level the reticle to the rifle, and torque the ring caps evenly in an alternating pattern to the specified value. Cantilever mounts are designed to push the optic forward over the handguard, which is what makes correct eye relief achievable on an AR.

Zero at 50 or 100 yards depending on your intended use, then confirm your holds at other distances with the reticle rather than assuming. Spend a session learning where the Hellfire DWLR-556 reticle puts your rounds at realistic ranges, because a reticle you understand is worth far more than one you have only read about.

Maintenance is light. Keep the flip back caps closed in transit, clean the glass with proper lens tools, and check mount hardware after heavy use. Battery changes for the illumination should be scheduled rather than reactive. Compare more glass, mounts, and accessories in our optics collection. Ships direct to your door, no FFL required.
