Hey guys I need some help, I just got my CA M24 back from a friend (been lending it to him) and he told me he couldn't get the hop-up chamber out to adjust it. It's been a while since I last used / touched an M24 internals so I was wondering if you could help me.
The barrel + PDI chamber won't slide out
I remember there being a hex screw that held it in place but it seems to have disappeared:
and for the life of me I can't remember what these two hex screws did.
(red oval)
It's really embarassing that I can't figure this out because I put it together but it has been around 1 1/2 years since I last handled it.
Anyone got any helpful input for me?
