The present folding stock adapter can be used with many types of military-type assault rifles that typically comprise a receiver extension, buffer and action spring. The present folding stock adapter can be used to add a folding capability to a standard stock allowing it to fold against a rifle's receiver when the weapon is not in use, thus reducing the overall length of the weapon. This reduction in length can facilitate its maneuverability, storage and transport in cramped quarters. The present device can also allow for the quick unfolding of the stock in order to allow the weapon to function and be fire normally.

A firearm includes a lower receiver storing an electrical power source and an upper receiver attached to the lower receiver. A pivot pin device provides a mechanical pivot point between the upper and lower receivers and a transfer of electrical power from the electrical power source in the lower receiver to at least one accessory rail attached to the upper receiver. The at least one accessory rail has electrical contacts that engage corresponding contacts on an electronic accessory device to supply the electrical power to the electronic accessory device.

The invention relates to handguns and is the firearm has the shorter length compared to systems in which the magazine is located in front of the trigger guard. Besides, the proposed firearm has the ability to quickly disassemble into the main components, which significantly reduces the dimensions of the firearm in the transport position. In addition, the magazine is also protected from loss when moving with the assembled firearm.

These results are achieved by the fact that the magazine of the firearm is located above the trigger guard, while access to the magazine is carried out only when the firearm is opened by turning the upper part of the receiver relative to its lower part. At the same time, the upper part of the receiver can be easily detached from its lower part to reduce the dimensions of the firearm during transportation.

Folding firearms have a frame having a trigger assembly and defining a passage containing a bolt, a barrel assembly pivotally connected to the frame, the barrel assembly including a barrel element defining a barrel axis, the barrel element including a barrel, a plurality of suppressor baffles forward of the barrel, and having an interior space, the barrel assembly including a sleeve encompassing the barrel, the sleeve having an interior defining an expansion chamber in gas communication with the interior space of the barrel element, a front closure and a rear closure at respective ends of the sleeve to provide a gas seal enclosing the expansion chamber, and the sleeve being rotatable about the barrel axis. The sleeve may be movable between an operating condition in which the sight facility is in a first position and a stowage condition in which the sight facility is rotationally offset from the first position.
