I had to google that gun just now, that is one hideous piece of plastic.

From what your saying it seems the easiest thing to do would be to replace the hop up entirely. Im not sure if that thing would take a standard m4/m16 hop up but they are on average, $30-50.

Granted you bring your ID this weekend you will be AV'd in the next 2-3 weeks im sure. I would personally not invest a dime in that monstrosity but that's just my opinion.
