Abstract
A barrel for an automatic firearm which cycles on recoil action is provided with a transverse pin extending across the top of the rearward portion of the chamber. This pin nests within the extraction groove of a cartridge sing during firing. On cycling, the transverse pin deflects the spent case downwardly towards an ejector which effects ejection of the casing.
