Justin,
Even a reasonably high condition rifle could have undergone some substandard "Bubba" gunsmithing. So I suppose the question is as follows. In your experience, do you tend to find more of those shenanigans with restocked and refinished guns than with used but decent condition originals? I ask because I inferred you might be more leery of "customized" guns. Yet my inference may not be what you intended to imply.
