Does the Sabra Mk.1 have the wrong ammo layout?

I recently got the Sabra Mk.1 for Israel and I was looking at its ammo placement and noticed that despire the fact thats its based on the M60A1, it has the base M60s ammo layout. It’s kind of been bugging me because I can’t take as many rounds as pervious Magachs based off the A1 model of the M60, and because it gets ammo racked more often due to that god awful ammo in the center of the turret basket.
