Odd to be discussing AR-15s/M-16s here, but...most of the newer versions (and all the clones) have a feature that projects out from the upper receiver behind the ejection port (a port buffer?) that deflects the brass away from the face of a left-handed shooter. I carried mine on a job many years ago and this feature wasn't commonly available then (early 1980s). I could have added a newer upper receiver to include this option, but FWIW, this gun is still all original "Colt", and I'd much rather spend the time and money on a nice double or an old Winchester. I've got nothing against black guns, but they aren't what I'm really drawn to.
