Muzzleloader systems include a pre-packaged propellant charge and primer for providing efficient loading and unloading of the muzzleloader. The muzzleloader accepts in the breech end the propellant containment vessel that abuts against a constriction portion with a reduced diameter portion. The propellant containment vessel having an end portion with a tapered surface that conforms to the constriction portion surface. A projectile is inserted in the muzzle end and seats against the constriction portion. The propellant containment vessel may be received in a removable breech plug. The constriction portion may be part of the breech plug or a separate component secured in the barrel by way of the breech plug. The containment vessel further comprises a primer mechanism that may be integrated into the proximal end of the containment vessel.

A hinged-breech weapon includes a receiver, a barrel part arranged to be tiltable around a rotational axis on the receiver, a front shaft removably fastened on the barrel part, and a bearing piece arranged on the rear end of the front shaft, when viewed in the firing direction of the hinged-breech weapon. The bearing piece includes rear bearing surfaces for pivotable mounting on the front mating surfaces of the receiver and a positioning device for adjustment of the position of the bearing piece relative to barrel part. The positioning device includes a clamping element movable in the bearing piece in the longitudinal direction of front shaft and adjustable by a control element for mounting on a stop arranged on the barrel part.

A barrel breech lock and mechanism for a projectile launcher chat uses a launcher body, a lower rail extending forward and under the launcher's barrel breech and a pivotally mounted latch plate. Extending downward extending from the latch plate is a front handgrip. Disposed between the lower rail and the latch plate and directly above the front handgrip is a locking mechanism that selectively blocks rotation of the proximal end of the latch plate. In two embodiments, the locking mechanism is a biased lateral push button or a biased sliding button. When the lock mechanism is activated, the proximal end of the latch plate may be rotated downward by a twisting force applied via the from handgrip. Disposed between the proximal end of the latch plate and the barrel breech is a second lock mechanism that includes a pin. The end of the pin engages a stop surface formed on the barrel breech when axially aligned in the breech void area. The first lock mechanism can be easily activated with the hand holding the from handgrip. Because the first and second lock mechanisms must be sequentially activated in order to open the barrel breech, the operation of the projective launcher is safer.

A firearm having a fixed magazine uses a latch to secure upper and lower receivers to one another in a closed position. The upper and lower receivers can be pivoted relatively to one another into an open position providing access to the magazine for loading by rotating the latch to release the upper and lower receivers from one another. The latch includes a hook spring biasing a hook contact surface of the latch to engage a hook receiving surface of a receiver when the receivers are moved from the open position to the closed position.

An ammunition holder and loader device for shotshells for a shotgun has two adjacent chambers separated by a selected spacing and has a planar body. The body has a pair of cartridge receptacles, each having a resilient retainer element configured to removably retain a rear portion of a shotshell against limited extraction force and to enable removal of the shotshell in response to deliberate force greater than the limited force. The receptacles have opening facing opposite directions.

A firearm (1) comprising a firearm frame (2) which delimits at least one first friction surface (6, 6′); one barrel (4, 4′), mounted to said frame (2) in a rotatable manner (A1) between opening and closing configurations and comprising an abutment appendix (8); and an adjustment device (10). Such a device comprises: 1) a second friction surface (12) placed in a sliding contact with the first friction surface (6, 6′) to oppose a resistance to the rotation of the barrel (4, 4′) between the configurations; ii) a contact surface (14) with the abutment appendix (8); iii) an adjustment member (16), longitudinally movable (LI, L2) for modifying a relative distance between the second friction surface (12) and the contact surface (14), thereby adjusting the sliding friction between said friction surfaces (6, 6′, 12); and iv) a maneuvering element (18) rotatable in discrete adjustment positions, interacting with the adjustment member (16) to move it by a constant pitch at each angularly adjacent adjustment position.
