Is this sight any good?

My son works at a pawn shop and gave me this sight. He said he only gave $5 for it and it's been on the shelf for a few months. It is a UTG CQB Red/Green dot 6.4" in length and 30mm tube diameter no magnification. Has the quick detach lever lock mounting deck and sunshade with flip up lens caps. Would this be something I could mount on my 835?
Does anyone know what base my 835 would take?

If I'm not mistaken that scope is made for air-soft guns.

Thanks EMSDJ2, Thought I may have had something good. But then what's new?
