The invention relates to firearms, and more particularly to a caseless bolt-action firearm. A caseless bolt-action firearm comprises a receiver (1) with a support (2), a bolt (63), a firing pin (36), a trigger (28), a magazine latch (27), a safety catch (31), a safety catch bracket (24), a trigger guard (3), an add-on stock (6), a grip (14), a magazine (15) and a barrel (18), wherein in the front part of the receiver (1) there is mounted a weapon chamber (17), and the bolt (63) contains a guide rod (41) for a conical bolt bushing, a triple-layered rifled cartridge (45) and a triple-layered smooth cartridge (44). The invention makes it possible to increase the operating reliability of a caseless bolt-action firearm in difficult conditions, easily eliminate delays, simplify loading and unloading, enable the firearm to operate reliably under combat conditions with forced feed of ammunition, including soiled ammunition, improve the stability of the projectile trajectory and increase firing accuracy both from stable positions and in the case of point shooting.

A charging slide for carrying a bolt and latching a firearm in a folded position. The charging slide comprises a body, a projection, and a grip. The projection extends away from a first surface of the body along a first axis. The projection is configured to engage the bolt. The grip extends away from a first side of the body along a second axis oriented transversely to the first axis. The grip comprises a surface configured to engage an edge of a slot in a handguard of the firearm when the firearm is in the folded position. A receiver assembly and foldable firearm comprising the charging slide are also included.

A rimfire takedown firearm that may utilize removable barrels of different calibers. The disclosed firearm does not require a barrel extension, instead providing positioning of the barrel that is sufficiently precise and repeatable. Tensioning of the barrel is provided passively during installation of the removable barrel, without need for adjustment or additional tightening. Securing the removable barrel to the receiver does not structurally involve the fore end, thereby avoiding harmonics effects associated with fore end interfaces to the receiver. The firearm takes advantage of an "underspaced" chamber arrangement to provide additional tolerance for manufacturing and assembly of the firearm.

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.

A collapsible firearm butt-stock assembly has a shoulder stock 18 coupled with a pair of guide rods 20, 22 slideable in respective guide holes 14, 16 of a housing 12. A locking mechanism including locking members engageable with guide rod recesses 26, 28 provided in the guide rods has an actuator 30 that is movable in the lengthways direction of the guide rods to release the locking members to allow sliding movement of the shoulder stock relative to the housing.
