I have been impressed with what I have read here and elseware reguarding Vortex, but I have just shipped one back, at my expense, to competitor. I bought the Crossfire 6-24 x 50 AO mildot to mount on an air rifle. I wanted something better than a Hawk or Leapers, but did not want to spend as much as another Leupold or Sightron would cost. The scope came last night, and this morning I checked it out befor mounting it. I focused the retical and then focused the objective at a bird feeder a known 15 yards away at 6 x. I then zoomed to 10 x and the scope was totaly out of focus, I mean colored blobs no detail. I refocused using the objective went up to 11.5 x, way out of focus again. To cut this short the scope would not hold focus while zooming on objects at mesured distanced of 15 and 20 yards. This on a scope rated at 10 yards and up.
Ok, the guy got a bad scope, tough, send it back, right ? Now heres what I find interesting. I called competitor for an RMA # and was told they would take the scope back but at my expence because they believed it was functioning correctly. Ok, the scope is definately going back, so do I ask for a replacement, or my money back. Next I call Vortex and speak to customer service, and describe my problem. I am told thats the way the scope functions. Look I'm not talking about zooming from 6 to 24 and needing to do a sight refocus, I am talking about going from 10 to 11.5 and having to do serious correction. "Thats the way the scope functions." How about, it would take three hands to use his scope, one to hold the rifle and two to work the objective and zoom togerher. Now he's 70% shure the scope is ok but if I send it in they will be happy to replace it. Also it is just a cheap scope and they build much better ones and if I'm willing to spend a couple of grand I can get one I will be realy happy with. Needless to say, I quickly made my decision not to ask for a replacement.
When you hang around with air gunners you get to see some $3000 Schmidt & Bender glass and a heck of a lot more $40 no name wonders, but you never see a scope that won't hold something close to correct focus across the zoom range. Or at least not one the company won't admit is defective.
