Shot an M4 while in Afghanistan and for those who don't know it has a collapsible stock which is the way I carried it normally and it is designed for right handed shooters. I'm a lefty, so when the necessity came to fire that thing "On short notice", that hot brass felt like it was tickling the end of my nose, but in reality was about 4 inches away. I can honestly say, I wouldn't be real keen on spending money on a gun where my face is about an inch from the ejection port during operation. Can't see a bullpup or any of those "shorties" in my future, but they look cool.
