Hi All

I need a little help with my crossman 600. It has just developed a leak and dumps the c02 out in about 4 seconds.

A quick description of the problem:

I insert a new co2 cart, screw in the end cap and as per normal you need to unscrew the end cap slightly, when I do this the gas leaks out, but it appears to come out inside around the pellet loader area.

I take it there is a seal in there, how hard is it to replace?

Has anyone experienced a similar issue?

Cheers
John
