Abstract:
1. A high capacity ammunition feeding system for use with a firearm, comprising: a body portion having a channel and a neck portion, one or more firearm cartridges being selectively disposed in said channel; a feed neck extension selectively connected to said body portion, said feed neck extension operable for transferring said one or more firearm cartridges from said body portion into said firearm, and a firearm, said feed neck extension further comprising one of a plurality of feed neck extensions operable for being selectively inserted into a magazine well of said firearm, and each of said plurality of feed neck extensions shaped so as to position said body portion at an angle relative to said firearm; a spiral following clutch drive arm operable for moving said one or more firearm cartridges from said channel into said feed neck extension; a cam stop winding knob connected to said body portion, and operable for rotation relative to said body portion in one direction; and a biasable member operable for transferring rotational force from said cam stop winding knob to said spiral following clutch drive arm such that when said one or more firearm cartridges are prevented from moving into said firearm by said feed neck extension and said cam stop winding knob is rotated, rotational force is transferred through said biasable member to said spiral following clutch drive arm, and tension builds in said biasable member, and as said one or more firearm cartridges are discharged from said firearm, tension in said biasable member rotates said spiral following clutch drive arm, thereby moving said one or more firearm cartridges in said channel and said feed neck extension.
