Bullet drop on semi-autos are same as those that are non-sniper rifles.
Bullet drop on it is pretty much ignorable unless you are in the extreme range, which I would not suggest people to try to play the game from.
Adding RDS/4x does not change the bullet drop characteristic. It only shows less due to the lack of zoom, like how bullet drop does not increase when using 12x scope but it is only exaggerated due to the zoom.
If semi-autos were capable of OHK at long ranges, there would be no need to use bolt action rifles since you get far better RoF, along with the ability of not having to scope out. You also get more ammo. You can also spam bullets in headshot line on running people with extreme ease if you do not have to constantly scope out and have to cycle the bolt.
The only way this would ever come in existence is if they make it like BF2, where every weapon has inaccuracy no matter how still you are and aiming down the sight. BF2 semi-autos had OHK headshots but they were inaccurate at range.
EDIT: /facepalm self for misunderstanding the topic. LoL
