The present invention relates to a method for improving flight stability, effective range, accuracy, and destructive force by moving the center of gravity of a bullet (shell) forward, and the bullet (shell). To this end, the front part of a counterweight jacket of the bullet (shell) is designed to be thicker or higher in density than the rear part thereof, so that the center of gravity is naturally moved forward. This structural feature stabilizes the trajectory by minimizing the yaw angle during flight, and increases the force of impact transmission to the target. In addition, a material having a low specific gravity is used inside a gunpowder contact part and the rear part to further strengthen the effect of moving the center of gravity to the front part. The present invention can maintain a stable flight trajectory in both ground and underwater environments, and maximizes the performance of a bullet (shell) to increase an effective range, destructive force, and accuracy.

A firearm suppressor also known as a moderator includes a number of coaxially joined steel baffles for dissipating discharge gasses. Each baffle can have an internal funnel structure having a central aperture through which the firearm projectile passes. Adjacent funnel structures form interconnected primary and secondary chambers connected by a port through a flange separating the chambers. A notch in the central aperture of one funnel structure directs flow toward the port on the diametrically opposite side of the next funnel structure. A radial hole through the funnel structure connects successive primary and secondary chambers. The flange is axially located to be radially inward from an overlapping joint between two adjacent baffles in order to provide structural support to the joint.

This invention provides a bullet clip for a bullet gun that prevents bullet deformation, comprising a bullet box, a spring, and a slider. The first end of the bullet box is closed, and the opposite second end is designated as the bullet inlet / outlet. A groove extending from the first end to the second end is provided on the inner wall of the bullet box. The slider is slidably disposed in the groove. The bullet box accommodates parallel-arranged toy bullets between the slider and the bullet inlet. One end of the spring is fixed to the first end, and the other end abuts against the slider. The slider has a retaining part, and the bullet box has a mating part. The retaining part engages with the mating part, thereby locking the slider at a certain point in the groove.

My invention pertains to firearms. It is an attachment for a bullpup rifle. The invention attaches to a bullpup rifle without making any permanent modifications to the rifle. It modifies the trajectory of ejected casings so that the casings travel away from the user to prevent injury. Prior art exists which can deflect casings, but those inventions either require permanent modification to the host firearm, increase potential to damage the host firearm, or are not securely affixed to the host firearm. My invention is new in that it can deflect casings without any of the aforementioned drawbacks of the prior art. It can also be easily repositioned to adjust the trajectory of the deflected casings.

This invention discloses a shell-breaking mechanism for a single-barrel shotgun, which uses a release spring to store energy and achieve shell-breaking. The weapon includes a receiver and a barrel assembly. The lower end of the barrel assembly is hinged to the receiver via a barrel seat. The receiver has a firing pin seat. The rear end of the barrel assembly has a cartridge groove. The barrel assembly has a guide hole, within which are an ejector and an ejector lever. The ejector and ejector lever are engaged. The rear end of the ejector has a ejection arm, and the end of the ejection arm has an arc-shaped ejection catch. The arc-shaped ejection catch engages with the arc-shaped protrusion at the tail of the cartridge in the cartridge groove. The lower rear end of the ejector has an ejector arc surface. The ejector is fitted with an ejector spring, the two ends of which act on the ejector and the guide hole, respectively. The lower front end of the ejector lever has an upper engagement surface, and the upper front end of the barrel seat has a corresponding lower engagement surface. The upper front end of the ejector lever has a return spring. The front end of the receiver has an upwardly extending release protrusion, and the lower front end of the ejector lever has a release surface.

The utility model discloses an intelligent anti -explosion bullet cabinet based on biological identification, include: anti -explosion cabinet body, install two door leaves on the anti -explosion cabinet body, install the display controller on one of door leaves, install face recognition camera and first fingerprint identifier on the display controller. The utility model first carries out face recognition and fingerprint identification through face recognition camera and first fingerprint identifier on the display controller, opens the door leaf, and the authorized personnel need to use the finger to stick on the second fingerprint identifier when taking the pistol, and fingerprint identification is carried out again, and it is ensured that the person who takes the pistol and the person who opens the door are the same person, and after fingerprint identification succeeds, the lock gun subassembly cancels the location of pistol, at this moment can take down the pistol from the layer board, and the bullet subassembly can drop a bullet every rotation, and the taking amount of bullet is also accurate and controllable, and the overall further improves the safety of bullet taking.

Some implementations include a perforating gun configured for transport with an internal detonator, the perforating gun to be used in a wellbore proximate to one or more subsurface formations, the perforating gun comprising: a detonator assembly positioned proximate to a ballistic initiator end of the perforating gun, wherein the detonator assembly includes the detonator; and a detonation cord positioned proximate to a receiver end of the perforating gun, wherein the ballistic initiator end is on an opposing side of the perforating gun from the receiver end; and an isolation cask disposed at the ballistic initiator end of the perforating gun, wherein the detonator assembly is recessed within the isolation cask.

The application provides a detonating cord lap joint transmission device, and relates to the technical field of oil and gas well completion, which comprises a positioning seat, an eccentric pipe arranged on the top working surface of the positioning seat, and a connecting pipe in communication with the eccentric pipe; the positioning seat is used for connecting with the tail disc of the upper jet perforating gun and fixing the upper section detonating cord of the upper jet perforating gun; the bottom end of the eccentric pipe is provided with positioning screws on both sides, and a coaxial center blind hole and an eccentric through hole are arranged in the eccentric pipe; the center blind hole is used for accommodating the end of the upper section detonating cord; the eccentric through hole is used for penetrating the lower section detonating cord; the upper end working surface of the connecting pipe is inserted into the lower end of the eccentric pipe, and is fixed through the positioning screws; the lower end working surface of the connecting pipe is provided with external threads; the application can be used without changing the size of the original perforating gun carrier upright pipe interface and the original intermediate joint, the use of the transmission pipe is completely cancelled, and the safety of the perforating operation is improved.
