Every AR I’ve ever picked up, first thing is a chamber check then on safe, unless I’m planning on using it for immediate action.
If there is already a mag in the action, I remove the mag and do the above.
If I’m loading it, I do the above and chamber a round.
An AR can’t go off with the safety on safe. No amount of bouncing will get it to go off unless the safety is moves to fire.
So, for me at least, on safe is the preferred method for every event except actively shouldering and firing the weapon.
