Benefits of Glass Etched Reticles and Illumination
Glass-etched reticles are superior to wire for several reasons, most notable is how much more crisp, fine and clean your view is when you look thorough the scope.

A glass etched reticle, also cannot be broken. Anyone who has shot enough has seen a wire reticle actually break within the reticle field. As the reticle design is etched into the reticle lens, it is static and cannot physically be broken.

All illuminated scopes with glass-etched reticles have the added benefit of zero internal light reflection which occurs to some extent in illuminated scopes with wire reticles.

This superior design requires an additional cost, but even if you don’t plan to use the illumination, the glass-etched reticle is a feature with value to the shooter.

Illumination comes into its own when shooting targets that are either naturally dark or made dark by light conditions such as shadow, dawn dusk, very bright light or night shooting with lamps or night vision kit.

Without Illumination a black reticle can be very hard to make out against the target. Illumination fixes this problem and gives immediate contrast. Adjust intensity according to the light conditions.

Features and Optics technology in more detail

Free custom SBT (Sig Ballistic Turret) with Tango4 purchases.

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

You can dial-in the exact shooting range of your target and hold the reticle directly on point-of-aim for unmatched accuracy on every shot you take. Pinpoint precision has never been so easy. If your target is at 300 yards, simply adjust the dial to “3” and know you are hitting the mark.

How you get the SBT
- Instructions in the box

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.

Stealth ID
Electro-Optics industrial design inspired by Sig Sauer 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.

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.

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