Things I liked:I have owned high-end air guns for 31 years and the AIRFORCE CONDOR is off the charts incredible! I LOVE IT! It is by far the most accurate and powerful air gun I have owned or scene in my life. I cannot recommend it higher! Things I would have changed:I prefer using the fiber optic open sights. The only thing I would change is to secure the rear sight in place better. The windage adjustment has a tendency to slide left and right after tightening. Also, I would prefer that the front sight also be green instead of red as I shoot often in low light and the green shows up much better. The gun is amazing and I am just nitpicking :-) What others should know:BUY THIS GUN IF YOU CAN! IT IS INCREDIBLE! I LOVE IT!
