Project salvo isues

Ok so i just bought myself a project salvo and ive been having a couple issues. First, the elbow feeder doesnt seem to fit and i think its not the elbow itself but the holes it fits into on the gun itself, i was just wondering if anyone has had similar problems and if so how did you fix it? second, i bought an aftermarket barrel and the shroud is really loose when i put it in, i read that this was a common problem with it and again, how did you fix this? i dont want to take the shroud off because otherwise what was the point of getting the salvo? I appreciate any advice very much thanks for taking the time to read this

What Mack said.  shimming the barrel with electrical tape is the only option for the US Army shrouds with aftermarket barrels.  Just wrap the barrel in on spot until it fits snug.  Do it right, and it is invisible.
