An improved minigun rotor comprised of distinct components that can be removed from the rotor and subsequently replaced is provided. The improved rotor includes a tail having a shaft, where a plurality of bolt tracks is attached to one end of the shaft; a camming section including a first cam and a second cam mounted on a sleeve, where the sleeve is configured to be removably attached to the shaft; and a barrel cluster head including a plurality of barrel apertures, where the barrel cluster head is configured to be removably attached to the rotatable shaft and secured to an end of the shaft. The improved rotor allows for each of the components of the rotor to be replaced (rather than the entire rotor) if a catastrophic failure occurs or the components need to be repaired or replaced due to wear and tear.

An electrically driven rotary machine gun includes a drive motor, a feeder delinker, a clutch, and a gun control unit. The drive motor is configured to rotate a rotor of the gun when receiving power. The feeder delinker is configured to provide ammunition cartridges to the rotor while being rotated. The rotor fires the ammunition cartridges while receiving them from the feeder delinker and being rotated by the drive motor. The clutch is configured to selectively engage the rotor and the feeder delinker while actuated. The gun control unit is configured to receive input from a user and provide power to the drive motor as a function of the input received from the user while and to actuate the clutch while providing power to the drive motor. The gun control unit includes a battery to eliminate the necessity of an external power supply.

A cooling rotor for a minigun that actively pulls gases and heat generated from firing the minigun comprises a front end with an axial opening; a rear end; a bore extending from the rear end to the axial opening in the front end; a plurality of longitudinally spaced, peripherally extending rotor segments; and one or more openings disposed between two or more of the plurality of longitudinally spaced, peripherally extending rotor segments whereby upon rotation of the cooling rotor gases and heat generated from firing the minigun are actively pulled through the one or more openings, the bore, and out the axial opening in the front end.

A safing sector for a minigun including a housing with an opening adjacent to barrels of the minigun, comprising a safing sector cover configured to cover the opening of the housing of the minigun; one or more retaining pin assemblies configured to retain the cover to the housing of the minigun; a safing sector slide member configured to slide forward and rearward relative to the safing sector cover; a safing sector slide control mechanism configured to impart the forward and rearward sliding movement of the safing sector slide member relative to the safing sector cover between at least a fire position and a safe position, where the barrels of the minigun may be rotated electrically without firing and without bolt assemblies becoming damaged.

Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.

Disclosed is a multi-barrel rotary toy machine gun powered by compressed liquefied gas, which relates to the technical field of a replica toy machine gun, comprising: a grip assembly (1), a gun body assembly (2), and a barrel assembly (3), which are successively connected, wherein a magazine assembly (4) for loading a plurality of BB balls (5) and continuously pushing the BB balls (5) into the gun body assembly (2) via an elastic thrusting device is inserted inwardly along an entrance of the gun body assembly (3). The internal space of the barrel assembly is sufficiently utilized, which innovatively reforms the space of the central barrel of the barrel assembly to a front-mount magazine and thus significantly increases the magazine space; as such, a considerable amount of BB balls may be loaded at a single time, which significantly improves user experience and increases fun of playing.

A machine gun top cover assembly includes a top cover door attached to a main housing. The top cover assembly defines a rear transverse track section and a front transverse track section for guiding bolt assemblies of the gun. As the machine gun rotor assembly rotates, the rear track section prevents the bolt assemblies from moving into position for firing, and the front track section guides the bolt assemblies into position for firing. A selector switch on the top cover door selects between: (i) a safe position wherein, each of the bolt assemblies are sequentially directed into the rear track section; and (ii) a fire position wherein the bolt assemblies are directed into the front track section. The top cover assembly can include a solenoid for moving the selector switch between the safe position and the fire position in response to an electrical control signal.
