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.

forward closed breech position in battery with the barrel and rearward open breech position, a cockable hammer controlled by a trigger, and a bolt release mechanism operably interacting with the bolt. The mechanism may comprise a user-actuated release button and spring-biased disconnect lever coupled thereto and selectively engageable with the hammer. Upon firing, the bolt travels rearward under recoil contacting and partially rotating the disconnect lever to engage the hammer, while simultaneously engaging the hammer which holds the bolt rearward. Actuating the release button fully rotates the disconnect lever to disengage the hammer from the bolt which returns to its forward position via a recoil spring to reclose the breech. A dual interlock safety in one position provided by the release mechanism prevents pulling the trigger and in another position prevents actuating the release button.

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.

A semiautomatic shotgun successfully uses the AR-10 receiver and the superior direct impingement gas system. A combination of locking lugs to maintain proper sequencing, a spring disposed inside of a gas impingement chamber, and a spring to cycle the action. Fouling is avoided using nickel-boron coated parts, permanent infusion of a dry film lubricant, and an angled gas port. A unique magazine feed lip and barrel extension feed ramp and the magazine maintaining the shells at a slight angle upward, and a bolt face having a rear facing partial bevel avoid jamming and snagging. The present invention also teaches raised gas tube and gas key to accommodate the larger bore of the shotgun. The combination achieves an AR-10 based shotgun which has the advantages of direct impingement cycling (less recoil, greater accuracy, etc) without fouling and/or jamming.
