摘要： An improved device for converting a semi-automatic self-loading handgun into a fully automatic weapon. The handgun is fixed in the front part of a case. An operating trigger is arranged in the case behind the handgun. Between the operating trigger and the trigger of the handgun a means is provided that causes pulling the trigger in a repeated series as long as the operating trigger is pulled. A hitting element is locked when being in rear position and when the operating trigger is in non-pulled state. A rocking arm causes the pulling of the own trigger when the hitting element is forced by a spring to move forward in the pulled state of the operating trigger. A locking assembly is provided and prevents forward movement of the hitting element, this locking starts when the slide has moved into rearmost position until the slide returns into its forward base position.

摘要： A system for firing reduced energy cartridges from a modern sporting rifle utilizes a bolt assembly weighing less than a conventional bolt assembly for such rifles and utilizes blow back for cycling the bolt assembly rather than gas operation. A bolt insert in a polymer bolt carrier of the bolt assembly has a projection that fits within a recess on the rear face of reduced energy cartridges. The reduced energy cartridges having a polymer casing, a rimfire power load for propellant, the power load recessed from the rear face of the casing. Tuning the bolt may comprise adjusting the weight of the bolt or the sliding resistance of the bolt assembly in the upper receiver. The bolt may be formed by metal injection molding with a polymer bolt carrier attached thereto.

摘要： In an exemplary embodiment of the present disclosure, a target marker for a firearm may comprise a module having a first portion, and a second portion electrically connected and coupled to the first portion. A light source may be disposed within and electrically connected to the second portion. An optical component may be coupled to the first portion at a first fixed distance from the light source. A circuit board may be electrically connected to the light source via at least one lead, wherein the lead may permit relative movement between the circuit board and the light source and may maintain a second fixed distance between the circuit board and the light source.

摘要： A barreled firearm having a mass-locked breechblock and a recoil-damping element which is connected on one side to a frame assembly and on another side to a barrel assembly including a barrel. A housing part of the barrel assembly is mounted in the frame assembly in an axially slidable manner. A support element stationary relative to the barrel is mounted in a breechblock housing or in the frame assembly in an axially slidable manner. Alternatively, a support element stationary relative to the frame assembly is mounted in a breechblock housing in an axially slidable manner. The breechblock housing is guided by the frame assembly in an axially slidable manner and the breechblock housing is supported by the support element by means of a spring element. This design absorbs or reduces recoil when a shot is fired from the barreled firearm.
