Gun Problems

[johnny933]

I use my hobby gun for back up and noticed this.....is it normal?
The metal piece on the inside of the gun barrel that has the pointed spikes
(hope I explained that right) moved when I was blowing out the gun. Is this normal or has it come loss. I havnt used it yet, but just wonated to know. Thanks for the help guys.
