Can this be a problem with Mark IV target?

I want to buy the exact same stainless steel mark IV target with threaded barrel but one of my friends said it can get loose overtime at the marked point on the picture due to taking it apart so many times. I tried to do some research but wanted to ask you for you opinion and experiences with the gun too. I’m only so careful because in the part of Europe where I live, these guns go for 1350$-1400$ if you can get them at all… Thank you for your help in advance!
