KSC USP.45 drop the BBs a few inch from barrel

KND · November 19th, 2008, 13:40

Hi ! Everyone ! I have a quick question to ask everyone for help regard to my KSC USP .45 . I just got this gun today from a trade. I fill the BBs and propane then ready to fire but unfortunately all BBs are jam in the barrel and if it's coming out, it just drop the about a few inch away from my barrel. I'm not sure about this problem. Hope everyone can help me. I`m pretty sure that the slide is go perfect and cock back perfectly as well but I really have no idea why the BBs jam in the barrel where the hop up ring there. Please help me everyone. Thanks in advance.

Cheers !

tune down the hop up? Inner barrel could be bent?

when you cycle through a mag, is there still gas in the mag or is it empty?

Is it a tightbore barrel??? might be bad BBs getting stuck in the tightbore.

Once happend because I had put too much silicon oil

Depends what BBs you are using.

Shoot the first BB, see where it gets stuck by taking it apart and magazine out.
The part where it gets stuck is your problem. (Ex. Stuck where the hop up is. Hop up is your problem)

Maybe try to tune your hop up down.

My USP had the same issue. I think it's hop-up related (make sure it's not up too high. I also had a tightbore so that may have been a factor. It was mostly fixed by cleaning out the hop-up and reinstalling it all.

Thanks dpuv, Your solution is really work now my gun work like a charm. Thanks everyone. I notice that if I move the hop up too high or too low, the gun won't fire the BBs, it has to be in the middle , not too low and too hight. Thanks everyone. Now the gun work like a charm. I really like USP right now. Looking to get another compact one soon.

Cheers !
