The Vudu 3.5-18x from EOTech has a plethora of features that make it a quality scope for long range shooting. The Vudu 3.5-18x contains a 34mm tube along with a High-Density glass. The oversized and precision precision-machined turrets, along with EZ Chek zero stop feature, 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. Long range shooting just became easier with the Vudu 3.5-10x riflescope.
