I saw a post online and a friend pointed out it's upside down but I'm not sure myself since I've never used it. Seems to be Wild Country atc. Does anyone know and how dangerous is this?

I mainly do indoor toproping and typically use BD Gridlock carabiner with it. But just wanted to know if this particular Simond extra carabiner that I have is ok to use with. Does anyone else here use it?
