First off I would like to say that this is not my gun, so my lack of knowledge does have some reason behind it. My brother bought it in '05, so I'm guessing that it's the '04 model. It worked fine for the first few times at the field, some bad shoot down and inconsistency's due to the awful stock reg, but not too bad as a whole. I hooked it up the other day to see if it would still work, dry-fired it a few times to break it back in. But when I tried to put some paint through it, it shot about five feet and that was it, barely enough power to push the paint through the barrel. And yes I did check the reg and adjust it to make sure it just wasn't turned down. I'm wondering what could be wrong with it. My guess is that some thing's a little off with the PDS or the detents.;0
