Aside from the random scattering of controls around the SA80 for manufacturing convenience, here's a couple of my favourite ergonomic design choices: Kar98k - bend in bolt handle obscures the sights when cycling. Kar98k - rearsight design presents a small notch in a big notch - guaranteed to cause high shots under stress. Springfield 03A3 - wimpy little foresight that's very difficult to pick up quickly through the apeture P90 - left thumb goes through trigger guard. Genius! What could possibly go wrong? Steyr AUG - pistol grip far too far forward; front grip too far back. Like a bloody hammerdrill. MP5 telescoping stock - erm, how the hell do you get vaguely comfortable with that?
