Vortex definitely recognized a problem and have attempted to make it right.
They have sat down and completely redesigned this line.
I have not been able to mount one and put it through the ringer but after handling the 3-9x40, you can tell an apparent difference.
Adjustments are much cleaner and seem to engage much better than the past, mushy turrets.
Glass is above average for this price range.
Housing is a much cleaner package. I hated the housing on the first gen models due to its bulky cumbersome build. The second gen models are definitely built cleaner with a better attention to detail. Another thing I hated on the first gen was the sight picture. Being able to see the scope tube walls and even illuminating the entire wall on any brightness setting was ridiculous, leaving a massive red ring around your entire sight picture.
The ocular bell is one of the biggest differences starting at the magnification wheel. They have widened the wheel making it much easier to grip while wearing gloves or in not-so-perfect conditions.
Running this scope through the magnification range is much smoother compared to the old model. There is no catching or rough adjustments as if something was grinding.
Adjustment of the diopter is fast and extremely easy. It carries a very wide adjustment range.
Again, running this adjustment from one end to the other was extremely smooth and definite.
The biggest question that remains for me and many others is the durability of this scope.
Hopefully I will be able to mount it on a few different systems and find out if the 2nd generation Vortex Crossfire has the guts.
