    SIG SAUER Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee.

  • LensArmor™ Icon

    Abrasion-resistant lens coatings for extreme durability ensure the lenses on your scope will stay sharp, bright, and clear.

  • LockDown™ Zero System Icon

    LockDown™ Zero System

    The LockDown Zero System is a stop-locking turret that allows a rapid return to Zero. After dialing up elevation for a shot at extended range, the LockDown Zero System eliminates worry over how far to turn the elevation dial to return adjustment to zero. Turret not only stops at zero, it locks at zero.

  • Motac™ Icon

    Motac™

    Activated through motion sensing technology, MOTAC immediately powers up illumination when it senses motion and powers down when it does not in order to extend battery life.

  • SBT™ Icon

    SBT™

    Perfectly matched to the ballistics of your shooting system, the SIG Ballistic Turret (SBT) is a custom laser-etched elevation dial for your SIG SAUER® Electro-Optics riflescope. Using inputs including bullet specifications, ballistic coefficient, muzzle velocity, elevation, and other environmental factors, the SBT system allows for the correct bullet drop compensation and pinpoint accuracy at any range. SBT dials are available on most TANGO and WHISKEY model scopes.

  • SpectraCoat™ Icon

    SpectraCoat™

    Highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.

  • Stealth ID™ Icon

    Stealth ID™

    Electro-Optics industrial design inspired by our legendary firearms; deflection armor trapezoidal surfacing breaks up the shape and visibility of the optic along with pistol slide serrations and grip checkering to add function to the form of all SIG SAUER electro-optics.
