Yes. They do still sell ammo. Mark has taken a regular job and Rita pretty much runs the store now.
It sucks that he is not an FFL anymore, I used to buy one of his surplus rifles every payday. The last few times that I have been there Rita hasn't even been there, just a younger guy that wears a drop leg holster.
I remember when Mark had is store in Edmond. I think I still have his card.
I never knew that he had a store in edmond, went to his shop while he was in MWC and then when he moved it to Del Clty.
