Rifling makes the shell spin, which (I'm not a scientist so idk the details) makes the shell lose energy and therefore speed and velocity, which are important to penetrate armour. However, during the prototype stage of the M1s development, the specification had been laid for the eventual arming of the Abrams with a 120mm cannon in the future.
