The built-in laser range-finding feature is great. So is the built-in bullet drop. I also hear there are ready-to-use stats for ballistics on common standard loads. The big problem: It has come loose every single time I have taken it to the range (6 times now). I tried blue thread-lock, and it STILL came loose. American Hunter did an article on this, and the writer found similar problems. Nikon apparently fixed them, but the fix was only temporary. The bottom line: you will need to get another mount if you plan on using this for hunting.
Pros: Laser range-finding to 600 yards
Cons: Mount comes loose EVERY SINGLE TIME
