Weapon Free Aiming

I’m sorry if this thread should be posted in requests. I was wondering if there was a way to make weapons to free-aim (somewhat like Smod’s free-aim).Since I’m not really familar with angles , I have no idea how to make it.Thanks.

Alternatively (and recommended by yours truly) you could use WAC, I find SharpeYe to be a bit too… dramatic.
