The inventive technology comprises a novel thermal indicator system that incorporates one or more thermogenic compounds that may be applied to a gun component and indicate the temperature of a gun component during and after use. This novel thermal indicator system may indicate the temperature at which the gun component will cause burns, is unsafe to store, or if a pre-determined threshold temperature has been reached resulting in a loss of firing accuracy, as well as imminent, or actual component failure.

An upper receiver assembly for a firearm having an upper receiver with an integral barrel nut, a handguard assembly and a barrel nut assembly with a barrel and lock nut is provided. The barrel is received by the upper receiver and is secured directly to the upper receiver using the lock nut. The upper receiver also includes an integral handguard mounting member to which the handguard assembly may be directly attached. The upper receiver assembly allows the user to attach both the barrel and handguard assemblies directly to the upper receiver, independently of one another.

The present disclosure relates to a launch tube including a barrel part 120 having a predetermined length through which a bullet 240 passes when fired; and an ammunition loading part 140 formed to be coupled to one end of the barrel part 120 and having an ammunition chamber 142 having an internal structure matching the shape of a cartridge case 220. In the launch tube, the ammunition 200 is loaded into the ammunition chamber 142, the cartridge case 220 engages the ammunition chamber 142, the ammunition-loaded launch tube is mounted on a separately provided launcher, the bullet 240 is fired, and then the launch tube is replaced with a new launch tube.

A disrupter cannon includes a barrel for launching a projectile. An insert may be used to launch a projectile of a smaller diameter than the projectile launched through the barrel of the disrupter cannon. An insert includes a bore therethrough, a breech-end portion, and a muzzle-end portion. The breech-end portion includes a channel. An O-ring is positioned in the channel of the breech-end portion. The muzzle-end portion includes one or more channels. A respective O-ring is positioned in each channel of the muzzle-end portion. While the insert is positioned in the barrel, the O-rings are configured to form a seal between an outer surface of the insert and an inner surface of the barrel. The projectile with a smaller diameter is launched through the bore of the insert.

A firearm training barrel for a replica gun, the gun having a slide and a magazine with a follower. The barrel includes an extended or extendable member positioned or positionable to simulate the presence of one or more pellets in the magazine, whereby the replica gun can be fired even after the magazine's follower has reached the top of the magazine.

The present invention relates to an arrangement (A) for balancing a gun barrel (20) of a vehicle mounted weapon system (C). The weapon system comprises the gun barrel (20) mounted to a turret (10) via a weapon cradle (30). The weapon cradle (30) is arranged to allow elevation movement of the gun barrel (20) about an elevation axis (Z1). Said arrangement (A) comprises a suspension system (S) configured to provide a torque opposing imbalance of the gun barrel (20). The arrangement further comprises an adjustment device (50; 150) for automatically adjusting the torque provided by the suspension system (S) based on imbalance of the gun barrel (20) so as to dynamically counteract imbalance of the gun barrel (20). The invention also relates to a vehicle with an arrangement according to the present invention.
