Air Arms Anyone else experienced Air Arms springer barrel-shroud creep?

The barrel-shroud on a TX200 HC I bought brand-new a couple decades ago started creeping forward on the barrel, of course in the middle of an FT match 🤬. PA corrected the problem under warranty only to have it recur, again in the middle of an FT match (of course) 🤬🤬.

I'm now having the same problem with my .22 Pro Sport (that I purchased used). 🤬🤬🤬 Anyone else experienced this problem first-hand? No speculations required, thank you.
