Anybody have issues with MP40 guard coming off?

The prop guard/housing on my mp 40 will randomly come off when it is running. Anybody else have this issue?

There is an o-ring around the base of the wet side that is either old or has become compressed. You can pop it out a bit with something sharp and see if that helps. If not may need to be replaced.

thanks, I’ll look into that, it feels loose compared to my mp10 when I take it off/on. Only a few months old and has always had this issue.
