It does around 625 fps with BBs, which is better that the nightstalker that does around 580 fps. Pneumatic rifles are by far the most powerful, I've never seen a break barrel do more than 40 ft/lbs and the more poweful they get, the harder they are to cock and shoot accurately.Then how powerful are the shots? If you get forty shots out of a 12 gram then the shots cannot be that powerful. Also which is the most powerful type of gun: break barrel, pneumatic, or co2?
