I do not know much about airsoft guns, but today I noticed that my inner barrel looked crooked on my ump.45. It appears to be pushed down and to the right. I also noticed that my shots have been going lower than where I aim. If this is a problem, I think it may have happened when I was trying to fir a suppressor over my gun. I think a bb possible could have filed to go through it and bounced back into my inner barrel. Does anyone know if this is a problem. If it is, would could I do to fix/accommodate for it.
