In a weapon system including a gun barrel and a bolt carrier, a cartridge feeder system comprises sprockets for stripping cartridges individually from a cartridge belt, and moving the cartridges in an upward direction against guide ramps for positioning the cartridge on a pedestal support having a profile for holding the cartridge in vertical angular alignment between the chamber of the barrel and a bolt lug of the bolt of the bolt carrier, thereby permitting larger cartridges to be fed to the barrel in the space between the open bolt and the chamber, which space can accommodate only smaller caliber cartridges in the horizontal distance therebetween, whereby as the bolt moves the cartridge into the chamber, the angular positioning of the cartridge is changed via the profile of the pedestal support, permitting safe entry of the cartridge into the chamber.

An automatic weapon system comprising: a gun barrel having a breech or chamber for receiving a cartridge; receiver means for providing the primary support frame for said weapon, said receiver means including at least first through third elongated tubular members mounted in substantially parallel relationship and a triangular pattern between inside faces of a forwardmost end cap and a rearwardmost back plate, said end cap including means for mounting said gun barrel near its breech end between said first through third tubes, said gun barrel extending from an outside face of said end cap, said first tubular member being uppermost relative to said second and third tubular members, the latter two being coplanar at substantially the same height; elongated force-transmitting means including operating rods longitudinally movable within each of said second and third tubular members; gas cylinder means connected between said gun barrel and said force transmitting means in each of said second and third tubular members, for applying forces generated by gases developed within said gun barrel during firing of said weapon to said force-transmitting means: bolt carrier means slideably mounted upon said first tubular member for moving a cartridge into the breech of said barrel for firing said cartridge, said force- transmitting means being responsive to the gases generated by said firing for applying a recoil force to said bolt carrier means for moving the latter rearward; and cartridge feeder means for feeding within a space allocated for cartridges of one caliber, cartridges having calibers relatively larger than said one caliber, said feeder means being mounted upon said second and third tubes, and being responsive to recoil movement of said bolt carrier means for directly positioning said larger caliber cartridges from a horizontal to an angular position between a bolt lug face of said bolt carrier means and the breech or chamber of said gun barrel, said cartridge feeder means being further operative with said bolt carrier means, whereby after the recoil cycle the latter moves forward for pushing said cartridge into said chamber of said barrel preparatory to firing said cartridge.
