Hey guys, I know it's been asked before but in this case; it's only leaking down the barrel when the bolt is not pumped back. I tried trouble shooting in semi-auto but there is no leak (trigger held down or not).
It's a pump-minimag so the powertube's got the spring instead of a spacer if that matters.
