I would not be interested in that either, but at least it has a better round than a 5.56. It is all a matter of purpose, e.g, I wouldn’t use a M4 as a sniper weapon, although it is not a poor choice for combat within 100m. On the other hand an AK-47 is probably better. It depends on whether you want to kill or wound.

Actually the one I mentioned IS 5.56

You can get them in 7.62X39 too,
but the AK 74 variants shoot the .223 / 5.56mm

At first glance it is easy to confuse AK74 with AK47
