Sig Sauer outfitted its 2-10x42 WHISKEY5 Side Focus Riflescope with high-quality optics and the HellFire TriPlex reticle. The HDX optics feature High-Definition (HD), High-Transmission (HT), and Extra-Low Dispersion glass, which provides true color, and maximizes resolution and brightness. Coated with SpectraCoat anti-reflection coatings, the optics exhibit high transmission across the entire visible spectrum, delivering bright and crisp images. To ensure that image quality is not degraded by environmental conditions or elements, the lenses are protected by the LensArmor coatings from abrasions and scratching and by the LensShield coatings from oil, water, and debris. Another highlight of this riflescope is its illuminated HellFire TriPlex reticle, which is located in the 2nd focal plane and offers a brilliant red center illumination. It features three medium posts and a fine crosshair.
To endure most outdoor conditions, the lightweight and durable housing's 1" maintube is made from a single piece of aluminum and provides a waterproof and fogproof performance. The windage and elevation knobs are knurled for slip-free operation and offer 96 MOA windage and elevation adjustment ranges with 1cm impact point correction. Also available with this riflescope is the Sig Ballistic Turret Dial (SBT), which features a precision tactical finger-operated knob. The Sig Ballistic Turret (SBT) is a custom laser-etched elevation dial that uses your bullet specifications, ballistic coefficient, muzzle velocity, elevation, and other environmental factors for the correct bullet drop compensation and pinpoint accuracy. All other dials and rings are also enhanced with knurling for a slip-free grip.
