The New Vudu 5-25 x 50 mm is ideal for the short platform rifles. At approximately 11.2 inches in length the 5-25x is one of the shortest first focal plane rifle scopes on the market. The elevation turret includes a push/pull locking system and EOTECH?s EZ Chek Zero Stop allowing for quick adjustments and return to zero. One unique advantage of the short design is that it provides the ability to attach either a clip-on night-vision or thermal device in front of the scope and still allow the user to make adjustments to the device without leaving the scope.First Focal Plane Single-Piece 34 mm tube XC?
