RE: Return? What would you do?
While I'd be aprettyirritated at the berk who sold me the gun for not mentioning it in his ad, I wouldn't let a small patch of rust like that turn me off on the gun either. Just clean it up and keep it well maintained and it won't get any worse. If you booger up the blue in that area getting the rust off, just get a bottle of cold blue and touch it up. In the big picture, it's no biggie.
