Which Kahles, Gen 1 or Gen 2, I know you said it was new, but it could be a NEW GEN 1, as I believe Ken only brought 4 GEN 2s in the US, and I have one and used it this past weekend.
Cause Kahles, acknowledged the S&B 5-25x was better but then updated the scope to bring it more in line with the S&B with their GEN 2 version.
A lot of it is color, and not actual resolution, as guys will bitch the NF doesn't have color but they have resolution. Not to mention anyone looking through a scope to judge resolution is doing little more than a personal eye test. Usually people who complain about "glass" in high dollar optics, do very little actual shooting.
Still the GEN 2 Kahles, is an upgrade.
The Beast is just awesome, that scope hits all the marks.
