Michael, I can see how others have exploited them for that purpose, but why Rigby started them, that's another matter. And there are better ways of accomplishing support for a barrel shoulder if that's their only purpose.

The explanation for their origins will always elude us I'm afraid. Unless someone unearths a currently unknown diary written by the guy who invented them.
