Castle nut staking

Awhile back there was a discussion on staking the buffer tube nut, pros/cons. Do people stake their barrel nuts? If you don’t stake the barrel nut but do stake the buffer tub nut can you explain the rational of one over the other. I personally don’t stake either. I do make a LIGHT mark with a chisel after torquing both so I can see if they are shifting/loosing up and make this part of my functions check everytime before firing the weapon. Thoughts?
