I have had Trijicon ACOG ,IOR,USO and Leupold Mark 4's......I bought this scope blindly , meaning I have never seen one in person .I Read countless threads reviews etc...after pulling this out of the box I was like WOW this thing is BUILT the knobs have solid audible clicks the finish is great the glass while not IOR good it is far better than the Mark 4 ....this scope is not for the whimpy if your looking for a light weight hunting scope this is not it .I will be mouting this tonight and if all goes well I will follow up with a range report by the end of the week one last thing I would like to mention the packaging is awesome a instruction cd ,reticle guide and how to use .cleaning cloth stickers ,bikini style lens cover etc. .OK there is one thing that did come as a disappointment MADE IN JAPAN....well that isn't a deal breaker but somewhat disappointing....stay tuned for a range report
