ABSTRACT:
A combined one piece cartridge case ejector and ejection spring useful in guns which have non-locking bolts for which conventional coil spring ejectors are not feasible. The device comprises a solid piece of elastic material such as hard rubber or nylon which is arranged in the path of the rearward travel of the spent cartridge case following firing and diametrically opposite from the extractor. This structure provides positive ejection of spent cartridge cases without damage thereto. The invention is of particular utility with cartridge cases with centers of gravity far to the rear thereof, which require high torque for positive ejection.
