    Abstract: A modular rifle includes an upper receiver assembly and a barrel assembly. The upper receiver, typically fashioned from aluminum, can be strengthened by insertion of a hardened metal liner insert inside the aft portion of the upper receiver. The upper receiver liner insert is secured within the aft portion of the upper receiver assembly by engaging screw threads on the liner insert with receiving threads inside the aft portion of the upper receiver and insertion of anchor pins into the aft portion of the upper receiver. The anchor pins impinge the liner insert such that it is prevented from rotating within the upper receiver. The barrel assembly is attached to the liner insert by engaging screw threads on the liner insert with threads within a barrel nut connector sleeve.

    Abstract: A firearm system includes lubrication notches are incised into portions of the frame and slide along the region of interaction between these two components. The notches act as reservoirs of lubrication and upon each cycling movement of the slide (firing of the weapon) one or more of the notches is placed opposite a corresponding portion of the slide or frame. The notches themselves are never exposed to the environment and thus retain the lubricant, unlike topically applied material. As a result, the frame and slide are lubricated during each cycle of the slide.

    Abstract: A drive, having a quick stop mechanism, for a breech is axially adjustable relative to a weapon barrel, and includes a motor, two counter-rotating chains and sprocket wheels that guide the chains. Engaging cams and control cams are integrated into the chains. A slide mounted at the bottom of the breech is displaceable transversely to the direction of fire and has a groove that the engaging cams engage to entrain the breech in a forward or reverse motion relative to the direction of fire. The engaging cam transporting the breech forwards is displaced from the groove while the control cam displaces the slide simultaneously to its center position via its ascent ramp, thereby allowing breech rest periods in the forward limit position. Firing causes the slide to move from the center position to the left hand side whereas it remains in the center position when no shot is fired.

  • Patent number: 8099893
    Abstract: In a first step, it is proposed that tunable transmitters and detectors (receivers) be included in a detection system and that a narrowband, preferably variable frequency signal be used in order to determine the frequencies for optimum injection into the electronics of a target. When the detection system identifies these frequencies, destruction can be initiated in the second step of the invention for a transmitter or receiver which is communicating with the target. For this purpose, once the optimum frequencies have been determined, a high-power signal is transmitted into the local area of the target at the specific/determined frequency. The evaluation unit, which is integrated in the detection system, controls the transmission frequencies, evaluates the harmonic signals, selects the optimum frequencies for an attack, and controls and checks the attack process.

  • Publication number: 20100139143
    Abstract: The semiautomatic pistol has a rigidly fixed barrel and sights attached thereto. The body of the pistol receives a breechbolt that moves axially in line with the fixed barrel. Cartridges are transferred from the magazine up to the action in the breechbolt, and spent cartridge cases are ejected out of a side eject port disposed on the pistol. Dismounting of the breechbolt is facilitated by a pivotal dismounting post at the rear of the eject port.

  • Patent number: 7721639
    Abstract: Methods and apparatus are disclosed for a locked machine gun that includes a casing, a barrel, a locking breech mechanism, an abutment and a quick change attachment. The locking breech mechanism has at least one locking body. The abutment holds the locking body or locking bodies of the locked breech mechanism. The quick-change attachment is used to facilitate the removal of the barrel and insertion and attachment of a new barrel. A first part of the abutment remains on the casing when the barrel is being changed, and a second part of the abutment is firmly connected to the barrel. The quick-change attachment is equipped to bring about a separation between the first part of the abutment remaining with the casing and the barrel with the second part. Also, the second part of the abutment has a curved section which controls the engagement of the breech mechanism in the abutment when the breech mechanism closes.

  • Publication number: 20090071053
    Abstract: In one aspect, a firearm system allows multiple modular firearm configurations, thereby providing significant customizability of the firearm by the user. All of the components necessary to fire the weapon are carried on a common receiver assembly. Interchangeable slide assemblies and handgrip modules can be detachably connected to the common receiver to substitute one firearm size, handgrip circumference, and/or munitions caliber for another. For example, the handgrip module can be substituted so as to change the size of the firearm and/or the slide assembly can be changed for purposes of changing the caliber of the firearm. In another aspect, an improved firing pin safety, which is capable of use in a one-piece machined slide, and which is additionally capable of being manufactured as a stamped sheet metal part, is provided.

  • Publication number: 20090064556
    Abstract: Slide retraction levers for use with firearms are described. In one example implementation, the slide retraction lever for use with a firearm includes a first handle and a second handle. The first and second handles are used to retract the slide retraction lever. Additionally, the first and second handles are positioned on opposite sides of the slide retraction lever. The slide retraction lever further includes a locking device that is associated with the first handle. Operating the first handle releases an engagement with the firearm. Additionally, the locking device is associated with the second handle. Operating the second handle releases the engagement with the firearm independent of the operation of the first handle.

  • Patent number: 7472507
    Abstract: A firearm includes a frame, a slide, and modular sear and trigger mechanism housings. The frame has fore and rear receptacles integrally formed therein, e.g., upwardly open compartments accessible from the top of the frame. The modular housings house one or more operational components of the firearm, e.g., trigger and sear components, and are configured for “drop in” insertion into the receptacles. Each housing also includes a set of integral slide rails. For assembly, the operational components are attached to the modular housings, and the housings are dropped into the receptacles and secured to the frame. The slide is operably positioned on the slide rails for reciprocating movement thereon. The frame is provided without integral rails and other features for supporting the operational components. Instead, the rails are provided as part of the modular, drop-in sear and trigger mechanism housings, which also support the operational components.

  • Patent number: 7389719
    Abstract: A firearm such as a semiautomatic pistol or handgun includes a barrel and a slide with a front aperture for rearward movement of the slide around the barrel during cycling of the slide between forward and rearward positions. A wire bushing is provided between the outer diameter of the barrel and the inner diameter of the aperture of the slide for positioning the barrel within the aperture during cycling. The wire bushing is a spring-like, generally round or O-shaped member (e.g., a bent metal wire) mounted within a groove provided in the slide aperture, with portions of the bushing being bent to lie out of the groove for contacting the barrel. The wire bushing reduces the tolerances between the slide and the barrel, thereby improving operation of the firearm, improves re-location of the barrel within the slide, provides for easier maintenance, and reduces mass, cost, and complexity.

A trigger is provided and a chamber is arranged behind the trigger when looking in a direction from a front end of the barrel toward the shoulder support. A movable breechblock has a closed position in which the chamber is closed off. At least one firing pin for firing a cartridge inserted into the chamber when the trigger is triggered is provided. A coupling mechanism connects the shoulder support or a swivel arm to the breechblock. The breechblock is movable by a pivot movement of the shoulder support or the swivel arm transmitted by the coupling mechanism. An axis of rotation of the shoulder support or the swivel arm is arranged within a space delimited by the breechblock and the trigger viewed across a length of the rifle.
