The present invention proposed a method to achieve the caseless ammunition firing with liquid propellant for automatic weapons. The weapons with this method were driven by a servo motor that led a slider (9) for linear reciprocating motion, and then the slider (9) drove a combustion chamber (3) and a rotary lock (4) to complete the projectile loading and the combustion chamber (3) locking. The combustion chamber (3) locking was done with the help of a fixed plunger (7).

A separated binary liquid gunpowder was used as a propellant. The constant liquid propellant injection pressure was maintained by a constant pressure regulator; and an electronic fire control unit (EFCU) precisely control two solenoid valves opening time in order to control the injection amount of the mixture. The gunpowder was injected through the nozzle on the plunger (7), and was ignited by an electronic igniter to launch the projectile.

A rotor for a firearm having a tracks and locks for interaction with at least one firearm bolt with a rotatable head and carrier body may have a reversible lock structure such that locks may be merely turned around in relation to the rotor when one set of lock bosses is worn by the interaction of the lock and bolts when firing. Drive and delinker gears may also be geometrically keyed to the rotor to efficiently divide torque across the gears and to maintain correct timing for the firearm.

A firearm system having separate frame, action, & lock systems is disclosed. The firearm system is closed, sealed, and inaccessible when in safe mode. The physical gripping of the firearm allows access to a lock input component which is then physically actuated at which point if a lock code has been input correctly, the firearm system changes from safe mode to firing mode thereby allowing use as a firearm. Upon physical release of the grip, the firearm immediately returns to safe mode.

A round of ammunition including projectiles formed in a stack and having an offset center of mass. Upon discharge, the projectiles are subject to a complex flight path and increased drag, providing advantages in controlling pattern and depth of penetration at a distance.
