The Vudu 5-25X50 is ideal for 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 EOTECHs EZ Chek Zero Stop. 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.
