EJECTION-ASSIST MECHANISM FOR AUTOMATIC FIREARMS

摘要

A barrel for an automatic firearm which cycles on recoil action is provided with a transverse pin (13) extending across the top of the rearward portion of the chamber. This pin nests within the extraction groove of a cartridge casing during firing. On cycling, the transverse pin (13) deflects the spent case downwardly towards an ejector (3) which effects ejection of the casing.
