Oh that brings back vague memories of opening an XP 110....
It seems to me these "bridge" /loop/clip pieces or whatever you call them, are attached inside of the shell of the gun in such a way that it is super annoying to open. And put back together. Yep.
Start prying. Er, praying. Both actually.
Take out all of the screws and try to pry around the pressure chamber and those loops and eventually you should be able to expose enough to remove them. Or open the gun half way, pull the relevant pieces out, fix them, and put it back together. Whichever is easier lol.
