In an extractor device (100) mounted in a breech (300) section of a slide with a lower part with functional elements for interaction with an upper region of a grip part (200) of a firearm with an extractor (110) mounted rotatably about an axis of rotation with an extractor claw (111) provided in the region of an end of the extractor (110) close to the barrel (210) of the firearm and a guide element (112) arranged in the region of an end of the extractor (110) remote from the barrel (210) of the firearm and interacting with an extractor spring (120) biasing the extractor (110), in order to limit a rotational movement of the extractor (110) by contacting a cartridge (400) newly supplied from a magazine. The guide element (112) is biased in the direction of a control link (130) by the extractor spring (120) arranged in an inner blind hole (113) of the extractor, said control link being configured in an extractor pocket (310) in the breech section (300) and forming a bearing of the extractor.

The invention relates to a firearm, comprising: a housing (1) having a barrel (2) arranged therein; a magazine, which can be inserted into a receptacle of the housing and which has cartridges; a breechblock (3), which can be moved relative to the housing (1) in the longitudinal direction of the barrel (2), for conveying cartridges out of the magazine into a cartridge chamber (4) located in the housing, and for conveying cartridge cases (5) from the cartridge chamber (4) to an ejection port (6) after a shot has been fired. An extractor (8), which is connected to the breechblock (3) and is preloaded in the direction of the cartridge case (5) by means of a spring (7), and an ejector (9), which is likewise connected to the breechblock (3), are provided for the ejection of the cartridge cases (5). The ejector (9) is arranged in a cylindrical ejector seat (10). The extractor (8) is arranged on an extractor seat (11), which is arranged for pivoting about the ejector seat (10). The extractor seat (11) can be fastened at different positions along the pivoting path in order to adjust the ejection direction of the cartridge cases (5).

A biased pivoting spent ammunition cartridge case extractor and retainer mechanism for blowback bolt firearms. The mechanism includes a distal arcuate hook shaped and dimensioned to intimately engage and nest into part of the circumferential groove in front of the cartridge rim. The hook remains engaged during blowback extraction of the casing from the chamber, and prior to ejection of the case from the firearm. The hook is formed onto the distal end of a rocking member secured to the bolt by a medial pivot. A compression spring bears against the opposite, proximal end of the rocking member thereby biasing the hook inwardly toward the counterbore seat on the distal end of the bolt into which the base of the case rests during extraction. A direct gas impingement system overcomes the biasing force of the spring to cause the case to be ejected.

A lower receiver that may be right hand or left hand configurable is provided. The lower receiver includes a static ejector that can be easily configured for right hand or left hand positions within the same lower receiver and a magazine button assembly having a left magazine button and a right magazine button that are operatively coupled together so that either magazine button can be pushed to release the magazine. This allows the gun builder to use this one lower receiver to build a right or left handed rifle.

There is disclosed caseless ammunition, composing a shell, a propellant placed in a shell chamber, and an igniter block. The body of the shell is made with a cylindrical part, which passes into a inclined surface of the leading cylindrical part, which goes into the rear cylindrical part, wherein: the inclined surface is made at an angle to the longitudinal axis of the shell body; the leading cylindrical part is made with a wall thickness; of the leading cylindrical part is 0.122D, where D is the outer diameter of the ammunition; the rear cylindrical part is made with a smaller diameter than the diameter of the leading cylindrical part; a ledge formed between the leading cylindrical part and the rear cylindrical part; the rear cylindrical part ends with a chamfer; an inlet interior cylindrical hole made in the body of the shell, into which an ignition block is installed.

Provided herein is an automatic or semiautomatic rifle having a short-stroke action. While the stroke-length of the action in conventional weapons is typically 2 to 3 times the length of the cartridge it fires, the stroke-length of the presented rifle may be less than 1.5 times the length of the cartridge it fires. The reduced a stroke-length results in a reduced receiver size and overall weapon length as well as weigh savings. Such a short stroke-length is provided by the use of a divorced chamber that moves relative to the barrel of the rifle. In contrast to existing weapons having a firing chamber that is fixedly attached to the barrel, the firing chamber moves forward and rearward relative to a rearward end of the barrel. In such an arrangement, ammunition cartridges may be inserted in to a forward end of chamber and then positioned against a barrel of the rifle.
