First, this is the ONLY part that will allow a marui style G18 BBU to take flat type gas routers. And so it's something like hen's teeth.
That being said, I paid 33USD + 21USD for shipping. And then I had to pay a $47.02 in tarriffs due to UPS and Trump. You can do the math on how much this friggin nozzle cost me. All that being said, I really hope it doesn't break- it cost me just over $100 for what is otherwise normally a $20 part.
