I wasn't aware until recently that Rural King even carried guns or ammo. I don't have one really close to me, but the next time I drive by the closest one (Warsaw) I might just stop in to see what they have.
Please consider calling ahead first. Not all Rural Kings sell guns at this time. Some of them have been selling them since early this year, others are getting ready to(Muncie), still others are a year or two out(New Castle). I guess only corporate knows for sure which store will get a FFL license when.
