How to tell if a feed neck is pressed in or not

[staf0s]

I have a pre2k GenX vert feed with a 2000 serial #. Just for knowledge sake, is there a way of being able to tell if this is pressed in? I mean, I can’t unscrew it so I’m assuming it is. Was toying with the idea of putting on one of those old school KAPP feednecks, or any brand from that era.

more than likely pressed in fixed feedneck. look at it from the bottom and see it theirs a seem where the hopper adapter meets the press in feed
