Good condition. Box open.

The Sig Sauer 1-4x24 TANGO4 Side Focus Tactical Riflescope is outfitted with quality fully multi-coated optics and a 5.56/7.62 Horseshoe-Dot reticle, which is located in the 1st focal plane and offers a variable illumination. The reticle offers an illuminated horseshoe and center dot, inward-pointing arrowheads, and a vertical post with ballistic marks for 5.56/7.62 cartridges. It is enhanced with their proprietary Motion-Activated Illumination function (MOTAC), which powers up brightness when it senses motion and powers down the brightness when at rest. The reticle features a full-field illuminated crosshair, no posts, and an extensive system of horizontal and vertical markings. Made of Low-Dispersion glass (LD) the lenses are designed to provide true color and to maximize resolution of images. They are also fully multi-coated to enhance the transmission of light and to deliver high image brightness.

To endure the toughest battlefield conditions, the 30mm maintube is machined 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 166 MOA adjustment ranges with 1/2 MOA increments. Also available with this riflescope is the Sig Ballistic Turret Dial (SBT), which features a precision tactical finger-operated knob with a fine diamond knurling and a slit read-out facing the ocular. 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 a fine diamond knurling for a slip-free grip, including a side focus parallax corrector and a fast focus eyepiece. The eyepiece also offers a low-profile zoom lever with a bright green mark for visibility.
