There is a multi-caliber weapon system. The multi-caliber weapon system comprises: a frame body, with a front body portion, a middle body portion, and a rear body portion, and including: a plurality of frame flanges, each frame flange being coupled to an interior of the frame body and extending upwardly therefrom; a barrel, removably coupled to the front body portion of the frame body, including: a plurality of barrel rings, each barrel ring being disposed around a circumference of the barrel and spaced along a length of the barrel, wherein the barrel rings are disposed on the frame flanges; a chamber, removably coupled to the middle body portion of the frame body, and removably coupled to the barrel; and a bolt, removably coupled to rear body portion of the frame body, removably coupled to the chamber, and including: a bolt face, removably coupled to a front bolt portion.

A portable item carrier and belt feed system is provided along with related methods. One illustrative embodiment includes a carrier and feed structure comprising a semi-rigid material with a divider support extending perpendicularly from a center floor section of the carrier. A belt of items is folded over the divider to reduce jams or misfeeds as the belt of items is pulled through a feed chute near an upper side section of the carrier and feed structure at a predetermined range of feed angles to the divider support. A latch disposed on a lid of the feed structure is configured for quick and easy access to the belt of items. A flexible outer container encloses the carrier and feed structure and can be coupled to a harness section configured to couple with a mobile structure. Additional embodiments include variants suitable for field manufacturing as well as portable manufacturing systems and methods.

Ammunition storage and feeding system for light weapons that facilitates a continuous loading of the weapon, thereby relieving the user from multiple magazine replacements, and reducing potential weapon stoppages, thus providing more reliable and significantly uninterruptable use of the weapon with respect to operating the weapon with conventional magazines. According to an embodiment of the invention, the system is configured to automatically receive interlinked cartridges from a carrying device (e.g., a backpack or other convenient device harnessed to the user's body) through a flexible or semi-flexible leading means, to successively extract the cartridges from the linking arrangement and to successively feed each extracted cartridge into a dedicated magazine in a First In First Out (FIFO) manner.

The present invention relates to a machine gun (1) comprising a feed channel for a belt (5) for ammunition (18), and a cover (2) for said feed channel, wherein the closing movement of the cover results in the longitudinal position of the ammunition (18) belt (5) being adjusted within the feed channel.

An ammunition holster that provides for the storage and deployment of ammunition for reloading incorporating a strip style loader. The holster includes a main body, makes use of the strip loader with an elongate pull tab, and further includes a flexible flap and gate wall. The main body comprises an open ended box configured to contain and stow a loaded strip loader. The elongate pull tab is attached to the tab end of the strip loader to provide a larger gripping area for the extraction of the strip loader from the main body. The flexible flap and gate wall attach to the main body to enclose the open ends of the box of the main body while the flexible nature of the flap allows the gate wall enclosing one open end of the main body to swing away to allow the extraction of the strip loader using the elongate pull tab attached to the strip loader.
