What Is The Hole For?

Crappy cell phone pic. The hole is elliptical with the major axis almost parallel to the receiver.

7/32"x11/64" (M x m) is my best guess.

No idea, at first I thought it was a pressure release hole from the chamber, then looking twice... it just looks like a nice hole to put something in and ask questions.
