Break Barrel Mag-Fire Ultra barrel end

[flyfisher]

I have a Mag-Fire Ultra that I haven't shot in about 2 years, I decide to get it out and shoot a bunch of pellets. It's .22 cal but I don't think ti matters for my question. First shot, the insert in the end of the barrel came shooting out. It looks like some kind of air stripper but there are no holes on the sides of the barrel. Now for my question: does anyone know what holds that insert into the barrel housing? There is a rounded tab on the insert that fits into a slot inside the housing but I can't figure out what holds that insert in. There are no threads on it and does not snap into place It does not look like anything is broken.
Thanks in advance

Well gang, apparently I must have been blind when I looked at that insert or just did not look at it carefully enough. It did indeed break. I mentioned that the piece had a tab that fit a slot in the end of the barrel. Well it had 2 tabs and one broke off, the broken tab is still in the end of the plastic barrel shroud, I don't know exactly how it broke. Because it has been hanging on my wall for 2 years.
I have another question pertaining to that insert. Looking in the end of the shroud/barrel, the shroud is solid at the end of the barrel and the outside of the shroud simultes vents but is solid. The insert looks like it could be a type of air stripper but the air would have no place to be vented. I've included pictures to show what I'm talking about.

The baffles are threaded on to the barrel and the shroud is more of a press fit. You should be able to rotate it around with some force and kind of walk it up. The challenge would be to get down in there to rotate out the broken baffles before you can remove the shroud. The baffles basically lock the shroud in place.

Customer service could hook you up with a new baffle if you wanted the original look. If you take off the shroud and get an aftermarket moderator the barrel is 1/2x20 threads. You will see a small step down in the OD but it’s pretty minimal. I will see if I can find a picture of it or take a picture later when I’m back in the office on Thursday

This is what the barrel looks like when the shroud is removed the arrow points to the step down in OD and I have a moderator screwed into this sample

Ok I think I got it now. In my picture of the inside of my shroud, that piece that is around the barrel end is actually part of the the piece that that broke out. In other words the piece inside my shroud and the piece that broke should be all one piece. Seeing it in 2 pieces now shows me how crappy that design is with only 2 tabs connecting to the threaded piece. Not sure what I'm going to do, either try to get that threaded piece out and order a replacement.or just epoxy that broken piece in place. So in order to use a moderator, you have to leave the shroud off, correct?
Thank you so much for the explanation. Much appresiated.
