Downward ejection explained

In firearms, downward ejecting refers to firearms which eject spent cases downward from the firearm's receiver, rather than the more conventional designs which eject the brass to the side. This feature simplifies use by left-handers,^[1] and can help prevent gases and debris from being ejected near the shooter's face.
