[SHÖCK]

I just bought a KSC USP .45 from someone here on ASC advertised as working perfectly and with 2 good mags and 1 leaking mag. I recieved the gun to find 3 leaking mags and one of them was broken (Rattling inside). The mags I can fix or replace. The safety was also not working but I hear this is a common problem -just frustrating since it was advertised as working.

The real problem I have is that I discovered that the hop-up rubber is shredded. I knocked out the pin that was holding the inner barrel into the outer barrel and got it to slide out about 1cm but it won't come any further. This is enough to see that the ball bearing is misaligned and the rubber has a big hole in it underneath the ball bearing and the area is deformed and torn. I'm guessing one of the previous owners torqued the hop-up wrench waaay too hard.

Now, I can't figure out how to get the inner barrel out any further so I can take out the old rubber bucking or examine it for further problems. The diagrams in the manual that came with the gun are for the plastic outer barrel USP compact version. This is the metal outer barrel and slide .45 version and the pictures don't match up. Anybody have any experiences with this?

Finally - where can I get a new rubber? Airsoftparts.ca lists it but for $18 and out of stock.
