Abstract: The invention relates to a self-loading grenade launcher with a cartridge belt feed which conveys a cartridge with pawls engaging in the cartridge belt of a cartridge belt. An inertia bolt runs forward along a path from a release position against the cartridge chamber under the force of springs and is fitted so as to slide the cartridge conveyed from the cartridge belt by the pawls into the cartridge chamber during this forward movement. A control system coupled to the inertia bolt and the slides converts the forward and recoil movement of the bolt into the transverse alternating movement of the slides. A firing device comprises a firing pin, tensioned by a percussion spring. A housing secured to the cartridge chamber extends along the bolt path and partially surrounds it, the longitudinal axis of which continues the central axis of the cartridge chamber.

Abstract: The present invention relates to a light-weight automatic rifle with a housing with removable attachments, specifically a longitudinally coaxial barrel, a grip with a trigger mechanism, a shoulder rest, a clip, and sights. The slide slides back and forth in the housing in back of the barrel and along a cheek, resting in its frontmost position against the rear end of the barrel and with locking components that securely engage accommodations in the housing. The housing is a hollow plastic housing and it accommodates a metal sleeve, which is coaxial with the barrel. The rear of the barrel is inserted in the front of the sleeve, and the accommodations are on the rear of the sleeve.

Abstract: A firearm. The rear end of the barrel is directly adjacent to the frontmost point traveled by a slide. The slide travels back and forth inside the weapon's housing. The outside of the barrel is fastened directly or by way of an intermediary to a housing. The area inside the housing (12) and immediately behind the rear end (22) of the barrel (16) communicates with the atmosphere through at least one gas-escape port (26 or 26' & 20).
