A weapon which has a modular design. The weapon is subdivided into weapon-specific modular assemblies which are designed as carrier units of the components. The modular assemblies include a weapon housing into which a breech system of the weapon and a striking mechanism is provided, a weapon cradle that connects with the weapon housing, and a weapon barrel module. The modular assemblies are connected to each other by rails and guides, by binders and holders, by pins, or by bolts and quick release fasteners.

The semiautomatic firearm comprises: a movable assembly (4) adapted to move against a return spring (10) by recovered energy resulting from pressure exerted when firing an ammunition (7), wherein the firearm comprises a stopper, a latch and a striker cooperating with a hammer (5) controlled by a trigger (6), at least one of a pivoting fork and a hammer used for locking the movable assembly in a compressed position of the return spring at a rear position of movement of the movable assembly, after each shot, an unlocking assembly (12) that is manually actionable and able to act on at least one of the pivoting fork and the hammer for releasing the movable assembly (4) and allowing the assisted return of the movable assembly (4) in order for reloading.

A weapon which has a completely modular design. For this purpose, the weapon is subdivided into weapon-specific assemblies which are designed as carrier units of the components and/or of the modular assemblies of the weapon. A first assembly can be a modular weapon housing. Said weapon housing has a carrier unit into which a breech system of the weapon and its components are built. Another modular assembly is a weapon cradle. Into this modular assembly the weapon housing module with breech system is integrated. The weapon housing module can be complemented with the weapon barrel module. The components are connected to the modular assemblies and the modular assemblies to each other by means of rails and guides and complementary rails and guides for the assemblies, by binders and holders, by pins, bolts and quick release fasteners.

Provided in various example embodiments is an apparatus, system, and method for improved control of selectable dual mode trigger systems for semiautomatic firearms, which may include a timed locking mechanism incorporated in the trigger system that ensures that the carrier is seated before the hammer is actuated, and that the anti-hammer-follow disconnect does not engage out of sequence. Such a mechanism ensures that the necessary steps occur in the proper sequence in the trigger mechanism, so that at any given time the trigger and firearm are ready for the next desired function to occur. The addition of a timed trigger lock mechanism to the trigger as disclosed herein ensures that the sequence of events in the trigger is maintained in the proper relationship, preventing misfires and jams. Such trigger locking mechanisms have applicability beyond dual-mode trigger systems, and may be applied in various forms to semiautomatic firearms generally.

The linear repeating firearm, with assisted ejection, comprises: means capable of recovering energy resulting from pressure exerted when firing an ammunition to move a movable assembly against a return spring, wherein the firearm comprises a stopper, a latch and a striker cooperating with a hammer (5) controlled by a trigger (6), locking means for locking the movable assembly in a compressed position of the return spring at a rear position of movement of the movable assembly, after each shot, a manually actuatable unlocking assembly (12) capable of acting on the locking means to release the movable assembly to allow the assisted return of said movable assembly to perform an ammunition reloading.

Said firearm is characterized in that the locking means are made up of the hammer (5), which cooperates with the movable assembly, to lock the movable assembly at the rear position of movement.
