Don't like it personally, but the proof, as they say, is in the pudding.....

A great many fabulous Mausers, Mannlichers etc have survived a century of hard use with deep milling of the front ring.
Well, many decades at least....

Couldn't bring myself to do it today though.

For one thing, many Euro sporters have crests, engraving, or vintage text on the front receiver ring, and cutting into it would probably be considered vandalism by most posters here.
