In the .63 Dev log video I noticed that the FNX-45 has an issue whilst reloading, chambering a shot, or shooting. Here is the timestamp to show where it happens at https://youtu.be/n7FyfXZHFyY?t=12m53s

I think the legacy recoil camera system is much better (I hate comparing DayZ to other games) but every game makes it where when you reload you stop aiming down sights completely. I think the system where you are aiming down sights constantly whilst the gun is hopping up from recoil, chambering a round, or reloading looks very clunky and trying to replicate this in real life is very awkward and is something that is hard to do.

As well as I think making it where when you hold right mouse button you zoom in but clicking right mouse button will toggle ADS, almost every third/first person shooter features this and it is very smooth for gameplay and is comfortable/easy to get a hang of.
