Removing reflex shroud from Bantam

The bantam I had I just heated it up and twisted it off...

‘I didn’t take any set screws out, they may be there to hold the outer sleeve to an inner baffle..

‘just a guess.

I'm not talking about the Moderator at the end of the shroud. I can remove that with no problem. I need to remove the entire shroud from the barrel.
 
It should just pull straight out, there usually an oring on the end of the barrel air stripper.

It would seem like it but there's something keeping it from sliding off. I applied as much pressure as I feel comfortable in pulling it off but it's a no go. I will just leave it be. I wanted to exchange the shroud with the shroud from my 177 cal because it has a threaded end so I could put a Huggett on the 22 instead of the 177.
