Two weeks ago I received my FX Impact .30 and I felt it was under powered and I tried adjusting it with the regulator and valve but I couldn't get to shoot it passed 850 fps. So I sent it to AOA. Unfortunately I sent it off before I found Ernest video on how to adjust the power. Well anyways it took a week and today I finally received it. The chrony numbers show that it averages 891 now and I was happy about that. I put the gun together with the barrel first then I screwed the air bottle in. As soon as the air tank opened up it started to gush air out through the trigger housing area. So I unscrewed it and tried it again but it did the same thing. Next I cocked the gun and screwed it in that way but still air was leaking out. It's so sad that I have to deal with things like this. I'm not a happy camper. Now I have to send it out again and what is worst is that we have a camping trip coming up. In a way I'm glad it broke now so they can fix the problem but I really hope that I don't run into things like this anymore. I actually have a video on it leaking but I will not post it for now.
