With a 4:1 zoom first-focal plane design, illuminated glass reticles, 30mm tube and revolutionary LockDown™ Zero System turrets, TANGO4 riflescopes are the ideal solution for mid to long range tactical engagements, designated marksmen, and hunting. A unified industrial design integrates functional components like LockDown™ Zero System (lockable turrets) and MOTAC™ (Motion Activated Illumination). Includes one FREE SBT™ (SIG Ballistic Turret) custom-lasered elevation dial calibrated to your unique ballistics and environmental conditions.
We have developed truly game changing optics for all types of shooters: military, law enforcement, hunters, and competitive shooters.
SIG SAUER Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee.
Abrasion-resistant lens coatings for extreme durability ensure the lenses on your scope will stay sharp, bright, and clear.
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.
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.
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.
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.
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.
