I was wondering about that. Except I was thinking whether engraving would compromise the strength of the casing (and whether that is actually an important consideration)That's what I'm inclined to think until we have more evidence. Engraving doesn't just put pits into the metal. It raises the metal surrounding the engraving, and this can be felt with the finger. I wager someone that experienced with firearms would realize that might cause the rifle to jam.
