All scopes of weapons moving very much

I know it might be from some addon, but I have no idea which one. So if anyone knows how to stop scopes from moving and be pretty still again, I’d appreciate the help.

Solution 1:
Every time you wanna scope pause the game, go to options, mouse and set the sensitivity to 0.0000000000000000000001
Solution 2:
Learn to no-scope.

why should I, this can be fixed somehow, because some mod did it all.
