A cylinder breech block device () of a repeating firearm has a breech block cylinder () pivoted in a system housing () of the repeating firearm for execution of repetitive action thereof and capable of being locked to said system housing () for firing a round. A firing pin () capable of being cocked by a tension spring is mounted for linear displacement in the direction of a cartridge () stored in a magazine () of a barrel (). Cocking of the firing pin () is effected by causing rotation, through a predefined angle, of a breech bolt handle () rigidly connected to a tension crown ring () that is pivoted on a central shaft () of the breech block cylinder ().

Cylinder breech block device of a repeating firearm

A locking block device () provided in the region of a cartridge chamber () of a handgun barrel () has a locking block () for releasably locking the barrel () to a breech prior to firing, and has a control member () having a control guide () for swinging out the barrel (), after firing, for the purpose of separating the barrel () from the breech, and further has a feed ramp () formed in the region of a stop member () of the locking block () for feeding a cartridge, stored in a magazine of the handgun, into the cartridge chamber () following ejection of a fired cartridge. A modular design capable of being adapted to meet specific requirements is achieved in that the feed ramp () is formed on a ramp member () capable of being separated from the locking block () and releasably locked to the locking block ().

Two-piece locking block device

In a recoil-spring device () in a handgun equipped with a breech and a recoil spring () in the form of a spiral spring, whose rear end abuts a rear stop member () on a recoil spring rod () and whose front end is mounted for movement along the recoil-spring rod () with contraction of the recoil spring (), support in an uncomplicated recoil-spring eyelet is achieved in that the front end of the recoil spring () abuts, at least indirectly, a rear contact surface () of a contact element () that is mounted for movement along said contact-spring rod (), while the front contact surface () is in contact with an internal surface of the breech of the handgun.

Recoil-spring device for a handgun

An exchangeable adapter assembly for a handgun includes a handle frame having a trigger and a handle, into which a magazine can be inserted. A quick changeover is ensured by the assembly in that in the rear and front regions of the handle frame at least one adapter element is provided which cooperates with a rear and front adapter piece of a grip enhancer for attachment of the grip enhancer 100 to the handle frame. In the rear part of the handle frame there is also provided an eyelet device which, when the grip enhancer is attached to the handle frame, positively engages a bore in the grip enhancer. A securing pin can be releasably inserted into the eyelet device in order to releasably connect the grip enhancer to the handle frame.

Grip enhancer assembly for handguns

In a key element () for locking a hammer gun or bolt gun () comprising a trigger rod which can be reciprocated by a trigger, the locked state of the gun is apparent at a glance in a conspicuous manner in that the key element () is a releasably securely attachable component of the gun housing.

Key device for guns

Magazine () for a firearm, in particular for a semiautomatic CO2 or compressed-air firearm, comprising a basic magazine body, a number of projectile supports () for the reception of projectiles () as well as a transport means for the projectile supports, whereas the transport means is designed for receiving the projectile supports () movably with respect to the basic magazine body, whereas the transport means is designed for moving the projectile supports () in a circuit, whereas the transport means has at least one endless transport belt (), whereas the projectile supports () are connected to the transport belt ().

Magazine for a firearm

A method for producing a breech slide of a firearm in a metal injection molding process. The process includes the following steps: a green body is injected in an injection mold. The green body is cooled. The binder is removed from the green body to form a brown body. Then the brown body is sintered.

Process for producing a breech slide for a firearm

An antidismantling device for preventing dismantling of a hand-gun when a cartridge is present in the barrel () of the hand-gun, the barrel () being mounted in a breech block (), and a guide pin (), which is biased at least indirectly in the direction of the longitudinal axis of the barrel (), is slidably mounted in a bearing () in the breech block (), and one end of the guide pin at least indirectly abuts a contact surface () for making contact with part of a cartridge (), and the position of the guide pin in relation to the breech block () when a cartridge () is present in the barrel () differs from the position thereof assumed in the absence of a cartridge () in the barrel () is created in that the guide pin () interacts at least indirectly with a safety mechanism () provided on the grip of the hand-gun in order to prevent dismantling of the breech block () when a cartridge () is present in the barrel () of the handgun.
