An automatic weapon system including a gas evacuation opening formed in a bore of a barrel, a gas evacuation chamber, a barrel immobilizing device, a slide, a weapon frame with guides for guiding slide movement, a return spring mechanism of the slide and the breech. The gas evacuation chamber is disposed at a near-bore space located at the barrel bore outlet, a front wall of the chamber located at the barrel bore outlet is attached at the barrel outlet and having a lower part resting on a weapon frame. A rear wall of the chamber is formed by at least one bridge assembly having one end attached to the slide and another end sliding along the barrel, the bridge assembly is formed by a substantially flat plate having a groove extending from the barrel to the frame and sliding along the barrel, at least one sealing gasket. The frame of the weapon serves as the lower part of the evacuation chamber, the slide serves as upper and side walls of the chamber, a downwardly directed ledge provided at the front of the slide.

The present disclosure provides systems, devices, and techniques that can be implemented at a gun, such as an electromechanical gun. The gun may include a barrel located within a slide and a cylindrical spring enveloping the barrel. The barrel may be configured to act as a guide rod for the cylindrical spring, and the cylindrical spring may be configured to bias the slide in a forward battery position. The gun may include an electronic component such as an energy store, a processor, or a circuit board, located under the barrel and forward of the trigger when the gun is in an upright position. The gun may include a physical transmission medium that electronically couples the electronic component with an additional electronic component located rearward of the trigger, and the physical transmission medium may be at least partially encapsulated by a trigger guard.

A system is disclosed for extending a recoil impulse of a gun. The system elongates the recoil impulse to spread the recoil energy over time and reduce felt (i.e., peak) recoil force. Although the system adds weight to a gun, the system reduces felt recoil beyond what is possible by simply adding weight to a gun by using an inertial weight on a spring to absorb and release energy. To prevent shaking, the inertial weight system is tuned to a gun so that the inertial weight hits a pair of stops at certain points in the gun's discharge action cycle.

A semiautomatic handgun includes various unique features to facilitate rapid, accurate shooting. Some examples of the handgun include a more compact recoil spring system, locating the recoil spring around the barrel while permitting rearward movement of the barrel in conjunction with the slide. Other examples include an automatic magazine release for releasing the magazine upon the discharge of the last cartridge in the magazine. Still other examples include a grooved or roughened top slide surface for facilitating slide manipulation with one hand. Further examples include auxiliary sight systems to facilitate determining the proper distance by which to lead a moving target. Other examples include a takedown tool stored within the handgun.

A customizable firearm system includes a chassis. A barrel assembly is disposed in the chassis. The barrel assembly including a trunnion and a barrel nut assembly. The barrel nut assembly includes an outer barrel nut sleeve and an inner barrel nut sleeve receiving a barrel. The barrel nut assembly is removably disposed in the trunnion. A bolt carrier assembly is disposed in the chassis. The bolt carrier assembly includes a backplate assembly and a pair of guide rods. Each of the guide rods have a first end disposed in the backplate assembly, and a second end disposed in the trunnion. A bolt carrier slidably disposed on the guide rod.
