Fix my gun Derya TM22 screw

I got the new Derya TM22 pro and after the first cleaning the middle top screw is very loose and doesn’t go all the way in.

It was pretty firm first time I opened it and now it is very loose. Should I change the screw or anything else?

Sounds stripped, helicoil time.

I stripped the threads out of my handguard and no matter how much I turned the screw it wouldn't get tight.

Installed a helicoil and it works great now.

If it was stripped, I think without top rail also it wouldn’t get tight, right? It works fine without that top rail, I think the screw is just a bit shorter than what it should be

When you remove the rail, the screw goes deeper into non-stripped threads I'm guessing?
