A training magazine has a body configured to be removably received in the magazine well, a motor connected to the body and operable to generate a motive force, an energy storage element operably connected to the motor and configured to store potential energy generated by the motive force, and an actuator operably engaged to the energy storage element and to the reciprocating action element, and operable to transmit the potential energy to reciprocate the action element. The reciprocating element may be a pistol slide. The energy storage element may be a spring. The spring may be a torsion coil spring having a cylindrical shape with opposed circular ends. There may be an input rotor operably connected to the motor and to a first end of the spring. There may be an output rotor connected to an output end of the spring and to the actuator.

In accordance with various exemplary embodiments, a firearm actuation system is provided. The firearm actuation system, comprising a housing, a guide, a contoured actuation handle, and a bolt. The system provides an actuation mechanism for an AR-15 which is engagable by a shooter where the AR-15 is in a shouldered firing position. The contoured actuation handle may be retained in the retaining slot to provide an action-open-position. The housing may also comprise a mounting rail with a plurality of grooves, where each groove may be configured with a unique indicator.

For an externally powered weapon, in particular a machine weapon and a machine gun, having at least one barrel, a recoil intensifier at the front end of the barrel is proposed to intensify a weapon return of the returning masses of the weapon and to generate and intensify a signal for monitoring, in particular functionally monitoring, the weapon. The recoil intensifier is of a flared form. The signal intensified by the intensification is used for example for counting the number of shots fired, initiating an emergency stop function, etc. Depending on the further use, the mechanically intensified signal may be converted into an electrical signal.

A striking mechanism for triggering a firing pin of an externally or self-powered weapon that has a breech. The striking mechanism including a kinematic mechanism having a trigger rocker, a safety device and a release. The trigger rocker acts on the safety device such that the release functionally interacts with a striking hammer. The striking hammer having a telescopic pushrod. A spring mounted around the telescopic pushrod is tensioned when the breech is advanced and a catching edge of the release engages under a catching edge of the striking hammer.

In some embodiments, a firearm mechanism comprises a bolt carrier comprising a bolt carrier cavity, a buffer comprising a buffer cavity and a weight arranged to travel between the bolt carrier cavity and the buffer cavity. The buffer cavity comprises a damping mechanism comprising a reduction in a cross-sectional size of the buffer cavity. In some embodiments, the damping mechanism and weight comprise a valve arrangement arranged to pressurize the buffer cavity and damp kinetic energy carried by the weight.
