Drum Magazine Bolt Catch Actuator

摘要

The invention is an improvement to a typical firearm drum magazine cartridge feeding system. The improvement provides firearm drum magazine feeding systems with features that work together in tandem to actuate a typical firearm bolt catch. The firearm bolt catch is a common feature in many firearms with the purpose of halting the forward momentum of a firearm bolt. By actuating the firearm bolt catch, a firearm operator is aware that a drum magazine is empty of firearm cartridges. The advantage of this improvement is twofold. First, a firearm enthusiast or soldier utilizing a drum magazine with this improvement will enjoy the benefit of not taking an additional step to pull back a firearm bolt before reloading, and any person will enjoy the added safety benefit of knowing when a firearm is unloaded and safe to handle.
