Because you take things to litterally.

The size of the round is a key factor of what makes an assualt rifle useful, and veristile. Your weapons were full size rifle rounds as were Ak47's upon release. However sometime in the vietnam era the Ak47 was retooled and fitted with a smaller round to make it more managable. As i recall these were designated the AK47m or ak47 (modern).

Now the fact that some assualt rifles have used large rifle round rounds does not exclude them from being assualt rifles. There are other factors that are not limited to just the size of the round fired. Such as weight, recoil managment, magazine size, rate of fire, and general firing style.

The size of the round is key to what makes an assualt rifle great, but is not the only factor as you try to imply. I place such emphasis on the round size because on most modern assault rifles, and in fact on the STG44, they fire shortened rifle rounds. Was there really a need to hit on, or go into depth on the facts of weight, recoil, etc, when i chose to cover the heart of what makes up an assault rifle.
