I'm finishing up a Mauser project in 458 Win Mag and trying to decide whether to have a quarter rib installed or not. That decision got me thinking about where quarter ribs come from and what function they are designed to perform. They certainly look sharp but I'm noticing most of the high end guns being built these days don't have quarter ribs, while many of the high end guns from years ago routinely had them.

Anyone have a thoughts on the subject?
