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!
