Abstract

In a weapon system including a gun barrel and a bolt carrier, a cartridge eder 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.
