Abstract: A gun includes a receiver assembly, a magazine, a trigger assembly, a sear assembly, a blowback assembly and a reciprocating slide. When the trigger rotates, the first connecting member is capable of pulling the trigger slide to move linearly, and driving the second connecting member, the sear assembly and the force-storing slide to move linearly towards the same direction. Moreover, the force-storing slide compresses the blowback spring, and the blowback slide receives a restoring force of the blowback spring to drive the reciprocating slide to move backward. The gun could achieve a simulation effect of rotating actions of the trigger, as well as a simulation effect of blowback actions of the reciprocating slide.

Abstract: An apparatus for loading cartridges into a magazine comprises a setting mechanism including a sleeve, a body, a setting tool, and a link. The body may be slidingly disposed about the sleeve so that the body and the sleeve can slide relative to one another along a sliding axis. The body may translate between an upper position and a lower position along the sliding axis. A first end of the setting tool may be pivotally coupled to the sleeve for relative rotation between the setting tool and the sleeve about a forward axis. The setting tool rotates about the forward axis as the body translates between the upper position and the lower position.

Abstract: A fuze for a projectile intended to be fired by a cannon by ignition of a propellant charge using an electric igniter. This fuze is allowed to pase from a safety position to an armed position following the fire by releasing at least two different safeties. This fuze includes a capacitor which is intended to be connected to the electric igniter and which charges during the ignition of the propellant charge, and also a computer which detects the charge of the capacitor in order to allow the arming of the fuze when this charge is greater than or equal to a reference value, the charge of the capacitor constituting a first fire safety.

Abstract: A cam race comprising a hardened material (harder than a material of an upper receiver) is provided to increase durability of a firearm. The cam race is fit within a groove within an interior sidewall of an upper receiver of the firearm. The cam race comprises a body that is fit within the groove, and a plurality of fastener pins extending away from a rear face of the body that fit within corresponding through-holes of the upper receiver. Distal ends of each of the fastener pins are deformed to form a riveted connection between the cam race and the upper receiver. The cam race defines a slide face along which a cam pin of the firearm slides during a firing process, thereby increasing the durability of the firearm against undesired formation of defects within the interior sidewall of the upper receiver.

Abstract: A projectile deployment system includes a projectile casing having a pair of sockets, each socket sized to carry one of a pair of anchors of an entangling projectile having a tether connecting the pair of anchors. Each of the pair of sockets is angled equally relative to a centerline defined between the sockets. One or more pressure sources is capable of generating a pressure wave capable of expelling one or more of the anchors from the sockets to deploy the entangling projectile from the projectile casing toward a subject. A controller is operable to activate one or both of the pressure sources. A sight is oriented along a target line, the target line being offset relative to the centerline defined between the sockets such that when the anchors are deployed from the projectile casing they exhibit differing flight characteristics.

An elastic return element reversibly deformable between a first and a second state of stress which correspond to the first and second positions of the screw, respectively, the stress of the first state being lower than the stress of the second state.

Abstract: Disclosed herein is a modified rifle bolt carrier allowing a selectively openable vent/valve at the location where exhaust gas is pressurizing the bolt carrier to control carrier speed under suppressed fire in a first valve position or unsuppressed fire in a second valve position. A valve core is disclosed which may be rotated 180° to a first “open” setting for non-suppressed fire from its position in a “closed” position for suppressed fire, and a third “median” position. The modified bolt carrier will allow an operator of the firearm to adjust for a suppressor without changing the gas block or having to modify or adapt the front end or barrel end of the firearm.

Abstract: Aspects of the disclosure are directed to manufacturing an insert-molded expanding projectile. Aspects of the disclosure include locating a portion of a projectile body within a converging tip mold, the projectile body including a metal jacket extending from a tail portion to a nose portion and surrounding an interior solid core. The metal jacket and nose portion may be tapered in a forward direction to an annular forward edge defining an opening to an undercut interior cavity. Melted polymer may be injected into the converging tip mold and allowed to cool thereby forming a polymer tip having a main portion forward of the opening and a tip retention portion filling the undercut interior cavity and having a shape corresponding to the undercut interior cavity to retain the polymer tip in place.

Abstract: A rifle stock has a frame, a body having a butt pad connected to the frame and operable to move within a range of length of pull positions, the frame defining a plurality of pockets, each associated with a different length of pull position, the body defining a latch passage, a latch having a nose, the latch received in the latch passage and movable between a retracted position in which the nose is clear of the pockets and movement of the body is enabled for adjusting, and an extended position in which the nose is received in a selected one of the pockets, a release lever pivotally connected to the frame and operably connected to the latch, and the release lever movable between an operating position in which the latch is in the extended position, and an adjustment position in which the latch is in the retracted position.

Abstract: Disclosed is a device for loading a cartridge into a magazine having a cartridge loader ramp and a magazine guide. A guide pin can connect the magazine guide to the cartridge loader ramp such that the magazine guide is slidably connected to the cartridge loader ramp about the guide pin. The device can further have a base and the cartridge loader ramp can be inclined with respect to the base. The cartridge loader ramp can have a top and a foot can be disposed on the top of the cartridge loader ramp. When a magazine is inserted in the magazine guide and pressed down, a cartridge on the cartridge ramp can partially compress the magazine spring. The foot can push the cartridge into the magazine. An adapter sleeve can resize the magazine guide for use with a variety of magazines.

Abstract: A multi-mode and/or multi-ammunition type weapon is described, whereupon being removed from a stored position is always initially in a default mode that fires one form of ammunition type, and can be quickly placed by a user into a different mode that fires a second, and different, form of ammunition type. When returned to the stored position, an integral ammunition type selector is automatically placed into an initial position enabling the weapon to fire one of the multiple ammunition types as selected by an integral ammunition sequence selector. The ammunition sequence selector enables selection of either the first or second form of ammunition type as the default ammunition type when the weapon is placed into the stored position. A shot sequence recorder is optionally included for recording sequences of ammunition types fired, providing an un-alterable record of firing events.

Abstract: A trigger mechanism that can be used in AR-pattern firearms has a hammer, a trigger member, a disconnector, a locking member, and a “three position” safety selector having safe, standard semi-automatic, and forced reset semi-automatic positions. In the standard semi-automatic position, rearward movement of the bolt carrier causes rearward pivoting of the hammer such that the disconnector hook catches the hammer hook, at which time a user must manually release the trigger member to free the hammer from the disconnector to permit the hammer and trigger member to pivot to the set positions so that the user can pull the trigger member to fire the firearm.
