Selected by the US Army for both the Squad Designated Marksman Rifle System and for US Special Forces, the TANGO6T represents the pinnacle of optical performance, precision and versatility. Designed for today's MSR platforms, the Scope features SIG's remarkable HDX optical system, which combines high-definition and high-transmittance glass for ultra-high resolution and light transmission. The glass features a full suite of premium coatings to reduce reflections, shed water and provide added durability. The DWLR6 reticle is an electronically illuminated reticle system that uses fiber optic technology to vary the light intensity of the central aiming point from infrared dim to HellFire bright for daylight illumination-resulting in a bright, defined aim point for precise shot placement. And because the reticle is on the first focal plane, you get the same accurate holds at all magnifications. The TANGO6T is assembled in Wilsonville, Oregon, to the highest optical standards, and is 100% waterproof and fogproof. If you want military-grade performance and durability, get ready to TANGO.
