As I took it apart to clean and lube before my first range trip I inspected the bolt staking, it was as I had seen it should be on various places on the net.
But.....the buffer tube nut had no staking, you can tell where it looked like someone on the production line made a light stroke attempt, like a strike mark, but that is it.

I guess I will take time to do this. I have read it can be important.

Anyone else with a Sport 2 find this?
