AGN I need help with Evanix disassembly [Question]

Need help with removing the barrel from my Evanix Giant select fire so I can do a deep clean and barrel polish.

Please see attached video. I’m stuck at this point with what to do. I can’t tell, should the barrel unscrew from the housing…? I REALLY don’t want to break this thing!

Thank you in advance. This forum has blessed me with knowledge and it is always appreciated!

 
I don't have that model but basically all Evanix guns but the REX line ,where the barrel is threaded in the Action,........ once you remove the twin grub screws you just slide the barrel out.
Thank you! What’s so weird is the grub screws don’t even look like they’re holding onto it in any way. I guess it’s just friction keeping it in place.

I really appreciate your assistance!
