Probably the castle nut on the buffer retainer. Mil spec is to stake the retaining nut on the buffer so it won't rattle loose. If you are never going to replace the buffer retainer or the buffer then it won't hurt. None of mine are staked but I also only shoot at paper and am not running and gunning.

This^^^^

It's easy enough to stake your own if you wanted to, I usually don't.
