First Vortex purchase. Just received this scope the other day and already having issues. After carefully mounting and leveling, to include bubble level install, I installed the supplied battery for the illuminated reticle. It appeared to work properly at first, but then after a few times of adjusting the brightness it just stopped working. I tried replacing the battery. No luck. I called Vortex, they offered to send me a new cap prior to removing the scope and sending it back. FINGERS ARE CROSSED Plus I have another 6-24x50 PST on back order.
