Vudu 1-6x is compact, yet fully loaded. Crafted with the 3-gun and serious hunter in mind, this is an optic that feels as much at home on the AR platform as it does on your favorite bolt-action rifle. The EOTech Speed Ring reticle allows for fast target engagement at low power, but at higher power provides the resolution and accuracy required to tackle longer shots. The Vudu 1-6x is the perfect solution for short to medium range applications that require the highest level of durability and accuracy.Exposed Optical Surface Treatment Lens Coating - Broadband anti-reflection coatingWindage and Elevation Increment Per Click - SR2, SR3 Models: Approx. 0.5 MOA / SR1 Model: Approx. 0.2 MRADTotal Elevation Adjustment Range About Factory-Defined Zero Reference - A 14.5 min MRAD or A 50 MOATotal Windage Adjustment Range About Factory-Defined Zero Reference - A 14.5 min MRAD or A 50 MOABattery Type - CR2032Auto Power Shut-Off, Typical Time Interval at Which Power Will Shut Down to Preserve Battery Life - Approx. 2 hrs Battery Life, Typical Time of Use at Middle Brightness Setting at Room Temperature - Approx. 500 hrs
