The EOTech Vudu 3.5-18x50 provides a robust 34mm tube, XC High-density glass, and is loaded with other performance features required to take that long-range shot. The oversized and precision-machined turrets let you quickly dial adjustments and return to zero, even in low-light conditions. The side-mounted parallax adjustment allows you to dial the reticle focus in for the most difficult long-range shots.
