This mod eliminates re-centering aim assist (yes, even on PC). When you fire a shot, your sights/dot will shift according to the gun's stability. This will make follow-up shots harder to put on the same target. 
You will have to manually re-aim your gun in order to hit the same target.

This mod is meant to increase difficulty when using semiautomatic fire and was created with the intention of increasing the skill required to use a DMR or pistol. Automatic fire is also affected, but its effect is almost negligible.
Stability and recoil stats have not been tweaked yet. This is simply taking out the re-centering aim assist. Accuracy remains unchanged.

The muzzle climb restriction has also been removed. Now your muzzle will forever float towards the heavens as you unload.

Yet another mod I made at 3AM, no balance tweaks have been made and there may be bugs. There's really no way to show a preview of this mod except through a video, but I'm not going to do that.

The purple filters seen in the examples are not caused by the mod. I just forgot to turn off my filter for those moments.
