Looking for a nut for my Barska ar scope

[Expendable Nate]

I have a barska retro ar scope Colt 3x clone. I'm missing the nut that secures it to the carry handle. I have been looking and i have had zero luck finding a nut that the adapter proper. Any ideas?

I was also thinking about picking up a cheap carry handle mount and see if the nut on it might be the same
