His "redneck" image is from a gallery of crufflers. I believe it's copyrighted, at that; I'll check with the owner, whose name is Gordon Greene. That's not a .50, by the way, it's a 20mm Lahti:

While he might look like a redneck, I don't think anyone makes it through Rensselaer by being a beer-swilling bubba.
