EOTECHs Vudu 1-10x28 offers a robust 34mm, one-piece aircraft aluminum tube and single-piece eyepiece that includes a removable throw-lever for fast changes in magnification. The low profile elevation turret includes a push/pull locking system and a capped windage turret for a secure zero. The illuminated, glass-etched reticle and first focal plane design allows for distance estimation at any magnification and lighting condition. The SR-4 incorporates the iconic EOTECH illuminated speed ring along with a hashmarked inner crosshair reticle that uses MOA subtension lines for ranging holdover and wind compensation. With a 1MOA center aiming dot, the clean sight picture provides improved down range visibility while still allowing the full use of the horizontal and vertical stadia lines for hold-overs and wind calls. The Vudu 1-10x contains an auto-shutdown feature that will automatically turn the illumination off after approximately2 hours of inactivity (no button pushes). This preserves battery life and eliminates the chance of accidentally leaving the illumination on.
