Things I liked: Very clear optics, I love being able to change the reticle illumination color. I replaced the piece of junk scope that came with my Gamo with this one. I have only fired around 50 pellets, but so far the scope is holding zero. The scope will return to zero too.
Things I would have changed: I am not able to use the flip up caps or the sun hood. The rear sights of the gun get in the way.
What others should know: This is my first mil dot scope and still learning the nuances of it. As I mention previously, I intentionally moved windage and elevation then return it to back to zero. Dead on, great scope!!!
