So I got my new barrel.  I took off the piece that floats up and down on the spring.  But I can't figure out how to get the inner barrel/hop-up assembly out, let alone into the new metal barrel.  There is some sort of pin holding it in but I'm not sure how to get it out.  Does anyone know?

Not sure how the hop up unit differs on the PTP's compared to the HK45/USP, but there's a little screw in the back between the barrel and where the spring guide sits. I had to take that out when I adjusted my hop up.
