This is a brand new product Vortex released this morning and SWFA is taking pre-orders on it. As far as how it preforms, that is currently unknown. However if it is anything like the Diamondback tactical, its a fair option. The eye box to me seemed critical above 12X.
Generally speaking eye relief was consistent.
Field of view is within spec and the image is to be expected from sub $400. Comparatively speaking, I would say the scope that comes to mind is Nikon's prostaff when speaking of the resolution.
Certainly is a noteworthy option for a tactical scope on a budget that is feature rich.
I had a diamondback for awhile and my observations are pretty much in line with Skylar's. I wasn't overly impressed with the glass quality, but it was an ok scope.
If you can afford to spend $700-$800, there are quite a few better options. The Gen 1 PST that ITRDM mentioned is a good scope. The $750 LRHS mentioned above is another good choice. Both are a considerable upgrade over the Vortex Diamondback. The Vortex PST Gen 2 3-15 can be had for around $750 used and it's a really nice scope as well.
