So I recently bought a Spyder Victor for my son’s first paintball gun to play at our local field but when we went to play it wouldn’t chrono low enough to use it. I have the Velocity screw backed out as far as it will go but it still shoots too hot. I need help getting it to shoot at 260fps, I have found different spring kits for it but not I’m not sure if that will work. I know it’s a cheap marker but I’ve got to make it work. Let me know what you think?
