The external mounting of the gun and other armament apparatus frees up cabin space, permits the gunner's window to be closed with the gun in a ready position, and permits a 0.50 caliber machine gun to be used an alternative to either a 7.62 mm mini-gun or a single barrel 7.62 mm machine gun adjacent the gunner's window.

Abstract: A cartridge feed tray for belt ammunition is modified to receive shorter ammunition and exclude ammunition of standard length by inclusion of an insert positioned along the forward containment wall of the tray. The insert carries a feed lip that fits through a loading port orifice in the feed tray to direct shorter ammunition downwardly as it is being advanced towards the weapon breach for loading.

Abstract: A spring-loaded feed mechanism for a paintball loader. The feed mechanism includes an inner spool and an outer spool. A torsion spring is positioned between the inner and outer spools. The outer spool includes a pressure wall, from which the torsion spring is located on one end of the spring. A retaining wall is attached to the inner spool and is located at the opposite end of the torsion spring. When an operator of a paintball gun using the spring-loaded feed mechanism discontinues firing paintballs, the feed mechanism is stopped. Simultaneously, during the deceleration of the feed mechanism, the torsion spring is compressed, which allows the mechanical energy of the rotating feed mechanism to be stored within the compressed spring. When the operator desires to fire the paintball gun, the feed mechanism is accelerated to the requisite rotational speed. The compressed spring is release, thereby allowing the spring to assist in accelerating the feed mechanism to the necessary rotational speed.

At least one ammunition magazine (26, 28) is arranged to the side of the rear part (22) of the canon and has an outlet (29, 31) for the ammunition belt situated in such a way that the latter can be conveyed from a rear part of the magazine and guided forwards along an underside (33) of the magazine and thereafter curved through ca. 90° about an axis substantially at right angles to the plane of the belt for feeding the projectiles to the loading mechanism (24).

Abstract: An ammunition magazine for beltless fed ammunition is disclosed. The magazine includes at least one endlessly guided ammunition guide chain to transport ammunition, and a chain tightener to tighten the ammunition guide chain with a predetermined chain tension. The chain tightener carries out a clamping movement in the direction of tightening to increase the chain tension and carries out a clamping movement against the direction of tightening to reduce the chain tension. To prevent slack from developing, (for example, during acceleration of the ammunition guide chain), the chain tightener is provided with a brake to influence the spring constant of the chain tightener as a function of the direction of tightening and the speed of the clamping movement.

Abstract: An ammunition feed device is disclosed for feeding beltless fed ammunition to a self-loading weapon. The disclosed device includes an endlessly guided ammunition feed chain to feed ammunition into the weapon. It also includes at least two deflection units to guide the ammunition feed chain. Additionally, the disclosed device includes a drive for intermittently driving one of the deflection units in order to intermittently feed ammunition to the weapon in the ammunition feed direction. To reduce the acceleration forces applied by the drive of the ammunition feed chain without changing the operating speeds of the ammunition feed chain, the undriven deflection unit is connected to a blocking device that substantially blocks movement of the deflection unit opposite the ammunition feed direction.

Abstract: Cartridges (5) are guided during a loading phase shortly before reaching the automatic cannon (1) onto a first track, which differs from the conveying direction of the conveyor chain (14) and are guided at a greater distance from the revolving drum (13) around the shaft (15) of the revolving drum, and conveyed on. In a firing phase, the cartridges (5) are guided shortly before reaching the automatic cannon (1) onto a second track, which differs from the conveying direction of the conveyor chain (14), are guided around the shaft (15) of the revolving drum (13), and are sequentially brought into a firing position directly behind the revolving drum. After having been fired and ejected, the empty cartridge cases (6) are caught and are transported on the first track into a magazine (4).

Abstract: A handling system for brass shell casings in an ammunition handling system. A shaft has a first sprocket and first hub and a non-circular gear mounted thereto, and because of the non-circular gear, rotates at a variable speed when driven by a power source. A second hub, coaxial with the shaft and rotatable independently of the shaft, has a second sprocket and a circular gear mounted thereto, and because of the circular gear, rotates at a selected speed when driven by the power source. The speed of the first sprocket varies between being equal to the speed of the second sprocket to being less than the speed of the second sprocket so that one end of a shell casing mounted on the two sprockets first lags behind the other end of the shell casing, then catches up to the other end of the shell casing.
