A barrel cooling system for a weapon includes a corrosion prevention cylinder between a barrel and cooling fins arranged around the cylinder.

Trigger groups for semi-automatic firearms have a frame, a hammer connected to the frame and movable between a cocked position and a striking position, the hammer being biased toward the striking position, a trigger element connected to the frame and movable by a user between a forward position and a rearward position, a selector connected to the frame and movable between at least a first position and a second position, a disconnector having a hammer engagement facility adapted to selectably engage the hammer, a disconnector control element movable between a first control position and a second control position, the disconnector being operably engaged to the disconnector control element, the disconnector operable to move in a first range of motion when the disconnector control element is in the first control position, and in a second range of motion when the disconnector control element is in the second control position.

The invention discloses an intelligent automatic firearm calibration method and system based on three-dimensional modeling and laser measurement. The intelligent automatic firearm calibration method comprises the following steps that S1, point cloud data and two-dimensional image data of key parts of firearms are collected; s2, performing feature extraction and spatial relationship analysis on the original measurement data set; s3, comparing the three-dimensional structure model with a standard three-dimensional model in a historical database; s4, performing spatial feature extraction on the position information by using a convolutional layer; s5, if the current calibration deviation value is not in the preset standard range, submitting the high-dimensional position feature vector to a cross-level feature interaction unit; and S6, when the calibration deviation value is within a preset standard range, adjustment is stopped. The intelligent automatic firearm calibration method based on three-dimensional modeling and laser measurement is realized by combining a convolutional self-attention network, laser high-precision measurement and a three-dimensional point cloud processing technology.

Unmanned aerial vehicle characterized in that one or more (fully) automatic firearms are mounted in a fixed-wing carrier drone for the purpose of combating other drones or cruise missiles.

The invention discloses an intelligent simulation confrontation system and method based on laser coding and tactile feedback, and belongs to the technical field of electronic games and simulation training. The system is composed of an intelligent simulation gun, intelligent sensing clothes and an internet platform in a cooperative mode, and unification of safety and immersion is achieved through double-laser coding emission (light condensation / light diffusion), dynamic damage judgment, multiple sensory feedback (sound / light / force / electricity) and a state linkage mechanism. The innovation points comprise that the double laser modules are respectively adapted to far / short-range strike; the internet platform supports parameter configuration and state uploading; the dynamic damage algorithm is combined with weapon types, distance attenuation and protection levels; the immersion sense is enhanced through touch electric shock and acousto-optic feedback; and automatic forbidding and array prompting of the gun are realized through Bluetooth / wired linkage. According to the method, the fairness, authenticity and expansibility of simulation confrontation are remarkably improved, and the core contradiction that safety and immersion cannot be achieved at the same time in the prior art is solved.

In one example, the disclosure relates to adjustable flip up sight assembly that can be adjusted vertically and laterally in particular, for an automatic firearm, comprising a front sight support element that is supported by an axle on a mount, in particular such that they can pivot thereon, wherein the front sight support element has an adjustment element supported on a spring element and releasably connected to a front sight, which contains a keyhole type opening through which the axle is inserted, wherein the adjustment element can be moved in relation to the axle against the spring force between two positions inside the front sight support element such that the keyhole opening prevents a lateral movement of the front sight support element along the axle when engaged with the axle, and allows the lateral adjustment of the front sight support element in a released position.

An automatic firearm is provided, which operates with a system which unlocks the rifle with a certain force and makes it ready for firing again by using this energy, while the mechanism accelerates backwards with the force created by the pressure formed in the barrel after the weapon is fired, and the idle parts in the mechanism move forward due to inertia, creating create kinetic energy and includes apparatus suitable for this system.

An automatic recoilless firearm includes a barrel (100, 600) and a compensating mass launch tube (102, 616) in which a projectile is accelerated in one direction within the barrel (100, 600) and is counteracted by a compensating mass accelerated in the opposite direction within the compensating mass launch tube (102, 616) to minimize recoil and further provide for automatic ammunition handling. The firearm also includes one or more bolts (604, 620) and a barrel configured to reduce or eliminate the transfer of momentum and mechanical energy to the barrel and / or the firearm body (610) during operation of the firearm.
