Things I liked:The build quality of this gun is definitely top notch. I own a Daystate air wolf, FX revolution and the air arms is not a down grade on quality. The magazine system and stock is my favorite of all my rifles. Things I would have changed:Clicks on power adjuster. It's basically high and low power. I would never trust any in between adjustments. I would also change the fill port to a standard foster fitting. What others should know:It's definitely worth the money. It will not disappoint you. Almost forgot.... it's really accurate too!
