EOTech Vudu Rifle Scope 5-25x50mm 34mm Tube First Focal Plane H59 Reticle Hard Anodized Black. 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.
