Rather than stronger, I would say more rigid.

That's being nuanced, the action itself is very strong which I would use to call capable cartridge wise.

Rigid is stopping as much flex as possible, ergo the narrow port of ports.

I may be wrong, but my approach has been with mine is to put a rail on it and have no bottom cutout on the stock.
Rail is dual purpose in more scope positions and can snap on and off easier.

Same idea executed a bit differently, can't prove it of course.
