A triple-barrel firearm includes three barrels in a triangular array mounted on a rear stock. The rear stock is connected to the firearm rearward of the firearm's trigger assembly by a hinge assembly. The hinge assembly in turn, includes a locking member and a manually-activatable release member whereby the rear stock can be pivoted between a first “fire ready” position distal with respect to the trigger assembly and a second “storage” position proximal with respect to the trigger assembly. The locking member automatically locks the rear stock in the first position or the second position. The release member unlocks the locking member upon manual activation thereof to enable pivoting of the rear stock from the first position to the second position or vice versa. The rear stock further includes an opening for a retainer for firearm accessories.

A double-barreled firearm having a slide having a slide body, a first barrel, a second barrel in parallel with first barrel, a firing chamber having a first firing chamber and having a second firing chamber and a mechanism for firing only one chamber thereof. The mechanism has a selector switch having a selector switch channel, two feed bar assemblies, two extractor assemblies and a retainer. The selector rod has a proximal end, a distal end and a feed bar notch. The distal end is in rotational communication with the firing chamber. The proximal end engages with the selector switch channel such that when the selector switch is pushed from side to side, the proximal end travels along the selector switch channel causing selector rod to rotate. The two feed bar assemblies are in communication with the feed bar notch of the selector rod. Each of the two feed bar assemblies have a feed bar face. The two extractor assemblies are in communication with the selector rod. Each of the extractor assemblies has an extractor claw and a claw pushrod. A linkage is in communication with each of the claw push rods. The retainer is in communication with the distal end of the selector rod and with the firing chamber.

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.
