"Ok", i thought... maybe the guys who made GFM-mod wanted to make it a little more realistic... if you wanna hit anything, you gotta aim down the sight of your gun.. sure, it´s much slover than the use of crosshairs, but it´s much more realistic...
Yesterday, when i was going through game settings, i found this "crosshair on/off"

So all this time i´ve been playing without crosshairs, when everyone else have probably had them on...
Dont i feel stupid now....
