Omega suppressor issue

[Txarrowhunter]

I took my son hunting over the weekend and threaded the omega on the end of the ruger American Grendel as I always do but when I tried removing it the whole sleeve/body of the suppressor started spinning whiteout the rear adapter unthreading off the muzzle. Basically it felt as if the body spun without anything else spinning. I understand the rear and front caps can be removed but I’m certain that the sleeve itself may have spun or is that not a possibility?
