This game as a very narrow sensitivity range, so it's probably correct. But tell me exactly what you are entering (a screenshot would be nice), and I'll see if it's right or not.
Only added the guns I had to start with, please let me know if there is a reasonably fast way to get the missing gun-types! (Shotguns, Marksman Rifles, Light Machine Guns)
One of the problems with many games is that I potentially need to play the game for a very long time to acquire all the guns/scopes. For games that either allow cheat codes or have a test range like BF4 it's a little bit easier.
Also for games that lack a separate sensitivity setting for ADS it makes a little bit less sense to add them, although it can certainly be useful.
