You think it's that much of an improvement? I've got to tell you...I've fired bullpups and I have a hard time getting over how awkward it is to reload them. You may be able to cram more accuracy into a smaller package, but if you can't do a quick combat reload during CQB all the accuracy in the world doesn't help.
