A portable firearm includes component parts such as a barrel, a locking mechanism, a grip, a stock and a magazine. The grip has a left and a right grip element, wherein the user of the firearm grasps the left grip element with the left hand and the right grip element with the right hand, in order to bring the firearm into a shooting position, preferably centrally in front of his body, in which the open end of the barrel of the firearm points away from the body of the user.

The present invention is related to an Assault Rifle Conversion Kit, which is characterized by being an alternative for modernization, updating and tactical adaptation to existing and new assault rifles through adjustments that involve minor changes in the weapon and that provide a tactical character for its use in special operations and of great demand. The present conversion kit mainly comprises six selected sets of stock set, tactical grip set, second grip set, cover set, reload handle set and forearm set which can be attached to different types of assault rifles, due to the versatility of adaptation they have.

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.

The present disclosure describes a foldable firearm that collapses into a folded state under spring pressure. The foldable firearm may include a foldable grip assembly. The foldable grip assembly may include a foldable pistol grip, a foldable trigger assembly, a folding bar, and a foldable hand stop. The foldable grip assembly may fold into the top shell of the foldable firearm. The foldable firearm may also include an ambidextrous charging handle assembly that may include a bottom portion, a top portion, a guide bar, and two opposing charging handles. The charging handles may be pulled to unfold the foldable firearm, and/or butterflied such that pivoting one charging handle causes the other charging handle to pivot. The first-pivoted charging handle may then be pulled rearwards to unfold the firearm. The first-pivoted charging handle may then be pulled further rearwards to rack the slide of the foldable firearm.
