This disclosure describes systems, methods, and apparatus for a selectable barrel support that can be inserted into a forend of a firearm stock to support a first barrel type and flipped, rotated, or otherwise moved to support a second barrel type (or third or fourth barrel types). Bull and tapered barrels are examples of two barrel types that the selectable barrel support can be used to support. The selectable barrel support enables a firearm owner or gunsmith to exchange barrel types on a firearm without having to switch out the firearm stock.

Modular stock for a firearm

A firearm barrel tray having a barrel channel and a firearm accessory mounting interface, wherein the firearm barrel tray is configured to be attached to a firearm stock such that the barrel channel sits on a first side of the firearm stock and the firearm accessory mounting interface is configured to align with a recess on a second side of the firearm stock.

The invention relates to an attenuation device for a handgun comprising a barrel, a cartridge chamber and a breech (2, 20), wherein the breech (2, 20) is operatively connected to the attenuation device or forms a unit with the same. The attenuation device comprises a closed or closable cavity (4, 16a), wherein a loosely arranged attenuating agent is present in the cavity (4, 16a). The invention is characterized in that the attenuating agent is a mixture consisting of a first component, in particular first granules (6), and at least one second component, in particular a filler (7).

Attenuation device for a handgun

A system to acquire, via sensor data, and correct the trajectory of a fired bullet before it leaves the fire arm by directing the bullet exhaust gases via actuated gas ports, located on and in the compensator, to the corrected orientation as determined by the sensor data. Furthermore sensor data is additionally taken after the firing of the bullet to update future corrections. This system would be attached or wholly integrated into conventional small arms to create a quick target acquisition and firing correction system for the fire arm operator.

The invention provides an experiment method and device for ablation and abrasion resistance of rapid-fire weapon barrels. The method comprises the steps that 1) an experiment device is prepared, wherein the device comprises a pipe, an explosion shock explosive box or an explosive feeding port, a heating device and a high-pressure gas device; 2) the rapid-fire weapon barrels are connected to the two ends of the pipe respectively, and inner cavities are communicated with an inner cavity of the pipe separately to form a sealed gas channel; the rapid-fire weapon barrels and the heating device arecooperatively installed; 3) explosion shock explosive is heated or ignited, and a burning compound is obtained through burning; 4) high-pressure gas and the burning compound enter the inner cavities of the rapid-fire weapon barrels; 5) the rapid-fire weapon barrels are heated and cooled to obtain the rapid-fire weapon barrels. According to the method, from three aspects of the temperature, atmosphere and abrasion, the real environment where bullets or cannonballs penetrate through the barrels is simulated, the accuracy of a detection result is improved, the detection work is simplified, and the working efficiency is high; the experiment cost is lowered, the labor amount is greatly lowered, and the labor cost is reduced.

Experiment method and device for ablation and abrasion resistance of rapid-fire weapon barrels

A weapon barrel of an automatic firearm is subject to bending oscillations during firing. A damping device is provided for damping the bending oscillations and to at least largely dissipate the kinetic energy of the bending oscillations by friction processes which are initiated by the bending oscillations, between two respective successive shots in the firing sequence.

Weapon Barrel and Damping Device

The weapon barrel (10) has a damping unit (20) for damping the bending vibrations (S). The kinetic energy of the bending vibrations is dissipated extensively between two sequential shots in the cadence by a friction process, which is released by the bending vibrations. The damping unit has a friction element (21) which stands in friction contact with a radial projection (24) of the weapon barrel. An independent claim is included for a damping unit for damping bending vibrations.

Die Erfindung betrifft einen Dichtungsring (100) zur Liderung eines Treibladungslagers (4) einer automatischen Schusswaffe fur hulsenlose Munition insbesondere gegenuber einer Stirnflache (S) eines Schusswaffenelements, insbesondere eines Verschlusses (77) oder eines Projektillagers (2). Der Dichtungsring (100) weist eine an die Stirnflache (S) zur Anlage bringbare Dichtungsflache auf. Diese Dichtungsflache weist einen ersten Bereich (A1) um die Ringoffnung (D) des Dichtungsrings (100) und einen zweiten Bereich (A2) um den ersten Bereich (A1) auf, wobei der zweite Bereich (A2) gegenuber einer Tangentialflache (T) an den ersten Bereich (A1) zuruckversetzt (α) ist. Die Erfindung betrifft ferner ein Treibladungslager (4) fur eine automatische Schusswaffe fur hulsenlose Munition, welches zumindest einen der erfindungsgemasen Dichtungsringe (100) aufweist. Das Treibladungslager (4) weist dabei vorzugsweise ein oder mehrere, insbesondere zwei, Treibladungskammern (5, 50) auf, welche verschlussseitig und projektillagerseitig mit jeweils einem Dichtungsring (100) versehen sind.

Dichtungsring und Treibladungslager

The invention relates to a sealing ring (100) for sealing a propellant charge magazine (4) of an automatic firearm for caseless munition, in particular with respect to an end face (S) of a firearm element, in particular a breech (77) or a projectile magazine (2). The sealing ring (100) comprises a sealing face that can be brought into contact with the end face (S). Said sealing face comprises a first region (A1) around the annular opening (D) of the sealing ring (100) and a second region (A2) around the first region (A1), wherein the second region (A2) is recessed (α) with respect to a tangential surface (T) on the first region (A1). The invention further relates to a propellant charge magazine (4) for an automatic firearm for caseless munition, which has at least one of the sealing rings (100) according to the invention. The propellant charge magazine (4) at the same time comprises one or more, especially two, propellant charge chambers (5, 50), which are provided on the breech side and on the projectile magazine side with a respective sealing ring (100).
