tough to tell exactly without a picture but in ex condition $350-400 tops.
at best $400 and that's gonna be hard. I have bought several of the 740s and 742s for less than $300. scope aint gonna get ya anything extra unless its a high dollar scope and like new. Other than that most don't care about the scope on a rifle cuz most times its coming off anyway
