It doesn't surprise me a bit that ineptitude is the feeling you get at Bass Pro. For a KNOWN good bunch of guys who are close to you, I would recommend Lock 'n' Load, located at about Eastern and Serene.

There ya' go! They're the place I told you about where black rifles are pretty common. Good people are common there too, and they probably know just who to call.
