Die Erfindung betrifft Schlosssystem für eine Schusswaffe mit einer Anordnung aus zumindest zwei Hebelarmen, wobei die Hebelarme nach Art eines Kniehebels mit einer Achse oder Welle gelenkig verbunden sind, wobei der so gebildete Kniehebel beidseitig eines Totpunktes in dem die Anordnung maximal gestreckt ist, schwenkbar ist, wobei einer der Hebelarme als ein Schlagstück für einen Schlagbolzen ausgebildet ist.

The proposed technology relates to an automatic rifle (10) that comprises: a receiver (12), a bolt assembly (110), a trigger mechanism (106), a buttstock assembly (100), a barrel assembly (104), and a grip assembly (102). The receiver (12) houses the bolt assembly (110) and the trigger mechanism (106). The buttstock assembly (100), the barrel assembly (104), and the grip assembly (102) are connected to the receiver (12). The automatic rifle (10) is characterized by the receiver (12) being a unitary body.

A conversion kit for converting a firearm to fire only non-lethal training ammunition comprises a barrel assembly and a slide assembly wherein the barrel assembly includes a barrel having a projection and the slide assembly includes a gate which interacts with the projection. The gate includes a member which is movable between a first 'safe' position wherein a firing pin of the firearm is blocked from impacting on a cartridge to a second 'fire' position wherein the firing pin is not blocked from impacting upon a cartridge in the chamber.

A modular magazine well insert system accepts and latches different types of magazines including front and side catch styles. The system includes a plurality of magazine well inserts each having a common mounting interface which interfaces with a mounting feature formed in a receptacle of the firearm stock. The inserts may have a common basic configuration with some different features adapted for use with different magazine catch features, such as latching levers for front catch magazines or lateral apertures to access side catch magazines. A universal latch stud slideably mounted in the stock comprises features which cooperate with each of the magazine well inserts to retain and release both catch styles of magazines in the insert.

The purpose of the invention is to accelerate the disassembly and reassembly of the firearm and to exclude the possibility of losing the locking mechanism during firearm disassembly. Said purpose is achieved by the frame locking system of a firearm which frame consists of an upper frame (1) and a lower frame (2) sliding into each other by means of projections that fit into grooves created in both the upper frame (1) and the lower frame (2). In the lower frame (2) along the firearm's longitudinal axis is located a double arm lever (5) which one of the lever's arms (51) ends in a vertical hole (25) created in the lower frame's (2) horizontal rib (24), and the second arm (25) ends in the opposite position to the projection (4) created in the upper frame (1). A spring (6) is placed between the horizontal arm (52) and the rib (24).

An interchangeable barrel assembly for a firearm including a novel barrel and tool assembly which are used with a receiver having an open aft end. The tool assembly is configured to be inserted into the receiver open aft end so as to engage the aft end of the barrel. Torque applied to the tool assembly thereby transfers torque to the barrel without transferring forces to the action. This enables the same action to be used with different barrels and the barrel may be removed without removing the receiver or other components of the modular chassis or accessories mounted thereon. Additionally, standard torque may be applied to the barrel for connection to the receiver and firearm precision is maintained.

Vorgeschlagen wird eine Waffe (100) mit einem Rohrbündel (1), umfassend wenigstens ein Waffenrohr (2, 3, 4), bevorzugt mehrere, sowie einen Verschluss (50), wobei nur eines der Waffenrohre (2) auf den einen Verschluss (50) fluchtend ausgerichtet ist und mit diesem schusstechnisch zusammenwirkt. Das Rohrbünde! (1) weist eine vordere, mündungsseitige Rohrhalterung (5) sowie eine hintere, verschlussseitige Rohrhalterung (6) auf und besitzt in einem Teilbereich (7) einen Steuerkörper (8) mit einer Steuerkurve (9), die umfangsseitig eingebunden ist. Über diese Steuerkurve (9) kann das Rohrbündel (1) in der Gesamtheit und unabhängig vom Schuss der Waffe (100) verstellt werden. Der Steuerkörper (8) wird bevorzugt elektronisch verdreht, wozu ein Bolzen (11) des Aktuators (10) in die Steuerkurve (9) des Steuerkörpers (8) eingreift.

Implementations of the present invention relate to apparatuses, systems, and methods for converting an M249-platform firearm to allow the use of 6.8mm SPC ammunition therein. The conversion kit comprises an adapted barrel, barrel extension, gas port, and bolt, which are each configured to allow rapid reconfiguration of the firearm between calibers.

Bolt mechanism for reducing a caliber of a firearm capable of operating with a bolt mechanism having a movement component transverse to an axis of a projectile barrel (5) of the firearm, the firearm comprising a support structure comprising spacers (E1, E2) and two sidewalls (C1, C2) joined to opposite sides of the spacers, the sidewalls (C1) and (C2) each having a guide grooves (8) formed in their inner surfaces facing the bolt mechanism, the guide grooves comprising a first portion (8a) transverse to said barrel axis, and a second portion (8b) parallel to said barrel axis. The bolt mechanism comprises a bolt comprising lateral bearings (24a, 24b, 24c, 24d) on opposite sides of the bolt, a first pair of lateral bearings positioned towards a front portion of the bolt and a second pair of the lateral bearings positioned towards a rear portion of the bolt, the lateral bearings received in the guide grooves. The front and rear lateral bearings being spaced apart by a distance (Xa) configured to allow the bolt to tilt around a bend formed by an intersection of the first and second portions of the guide grooves to allow assembly of the bolt in the firearm.
