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.

Provided is a hinged firearm receiver configured to operate with an AR-pattern Bolt carrier group, buffer, buffer spring, and buffer tube. The firearm upper receiver has an integral hinge that connects to a rear receiver body and provides an AR-pattern firearm the ability to have a folding stock to reduce length for storage or transportation purposes.

A compact firearm has a first frame portion including a barrel defining a barrel axis, a second frame portion including a firing mechanism configured to discharge a cartridge residing in a chamber of the barrel, the second frame portion pivotally connected to the first frame portion to pivot about a pivot axis offset from and parallel to the barrel axis, the first frame portion defining a first mating feature formed as a first surface of revolution about the pivot axis, the second frame portion defining a second mating feature formed as a second surface of revolution about the pivot axis, and the first and second mating features mating closely with each other to prevent relative movement between the first and second frame portions except in relative rotation about the pivot axis. The first and second mating features may be dovetail elements.

An assembly (10) includes a forward unit (12) including a mounting portion (16) for mounting thereon a firearm, the forward unit (12) defining a projectile shooting axis (20), and a rearward unit (14) coupled to the forward unit (12). The rearward unit (14) includes a retractable buttstock (24) that has a retracted position and an extended position. In the extended position the rearward unit (14) is pivotable with respect to the forward unit (12) about a pivot axis (26) which is tilted relative to the projectile shooting axis (20).

A firearm with tilting barrel-receiver assembly includes a frame and a barrel-receiver assembly pivotably mounted to the frame. The barrel-receiver assembly is movable between an open position and a closed position. A latching mechanism includes a latch that selectively engages the barrel-receiver assembly. The latching mechanism may be disposed in the frame in one embodiment. The latching mechanism is movable between a locked position wherein the barrel-receiver assembly is held in the closed position and an unlocked position wherein the barrel-receiver assembly is movable to the tilted open position. The latch may be spring biased into the locked position. The barrel-receiver assembly may be configured for complete removal from the pistol in some embodiments. An interlock mechanism formed by a movable safety may be provided which prevents the barrel-receiver assembly from being unlocked when the firearm is in a ready-to-fire condition.

A compact firearm has a frame including a barrel defining a chamber, the frame being movable between a closed condition in which the firearm is operable to discharge a cartridge in the chamber, and an open condition in which the chamber is open for loading, a latch movable between a latched condition to retain the frame in the closed condition, and an unlatched condition to enable movement of the frame to the open condition, a firing mechanism connected to the frame and operable in response to actuation to discharge the cartridge in the chamber, and a trigger element operably connected to the firing mechanism to selectably actuate the firing mechanism, and operably connected to the latch to move the latch to the unlatched condition. The trigger element may be operable to selectably actuate the firing mechanism in response to movement in a first direction.
