"It is a peasant's weapon with poor accuracy good only for close in fighting" which is what it was designed for as first the Germans then everyone else realised that 200yd+ accuracy was of less importance in a mobile war like that at the end of WW2. It's a great example of the "KISS" principle as well.
And as the Iraqis found out, when the enemy can see you from 2 miles away, accuracy IS important.
