Removing the Inner Barrel [SiG 552]
Yes I know, more run of the mill questions.
Today I disassembled my SiG 552 for the first time because I wanted to learn how it all got put together, as well, the first thing I'll be upgrading is the inner barrel to a 6.03mm or a 6.04mm. Problem is that inner barrel is attached to what I'm quite sure is the hop-up. I can't disconnect it by any means I've been doing, which is mainly just pulling as hard as I can on the bugger. Is it normal to be this difficult to get off, or am I just doing it wrong?
I don't really want to put this back together until I've at least learned one thing about it's insides.
Thanks in advance!
