My KAC LMG came in this afternoon. Seems nice and solid, looking forward to fielding it.

Question though, I noticed when I removed the outer barrel that the inner barrel and hop unit rotates pretty easily, it seems like the hole where the bb passes from the box mag feed tube into the hop up chamber could pretty easily become misaligned. Is the hop unit and inner barrel supposed to be so loose? Or is it supposed to be held in proper alignment? As it stands I'd have to use two hands to adjust the hop up - one to twist the hop up and another to make sure the whole assembly doesn't rotate. I'm not sure if all CA 249 style hop units are like this?

Sorry if this is a stupid question, my first LMG and did not come with a manual.
