I think the current scope mounts on the Hawkeyes are one of the best systems going. It would be a shame to make those rifles less heavy duty, which is just what would happen by adding additional screws to come loose.
As is, a guy can carry a previousy sighted-in backup scope with rings in his pack, and swap the scopes to be back in the hunt with 4 twists of a screwdriver.
The only benefit I see to a regular mount setup is to take advantage of the sloped LR bases, and since there are plenty of scopes out there these days with the built-in travel to get a guy way out there it would hardly be an advantage. Plus, extreme LR shooters aren't buying many sporter weight, controlled round feed rifles anyway.
