A monolithic barrel for a weapon has an integral suppressor. The barrel and integral suppressor can be machined from a single piece of material, which can eliminate the need to attach separate components to the barrel. The monolithic barrel has a barrel bore for firing a projectile that produces discharge gas. To suppress the discharge, the barrel defines one or more baffles separating expansion chambers toward a distal end of the barrel. The barrel further defines one or more channels along the length of the barrel that provide extend flow paths for the discharge gas from the barrel's bore. Greater reductions in sound can be achieved relative to the overall barrel length due to the integral suppressor.

A gun barrel assembly includes an outer barrel tube, an inner barrel liner, a barrel breech cap and a barrel muzzle cap. The barrel tube and the barrel liner each longitudinally extend from a muzzle end to a breech end, and have axial through bores, with the barrel liner being disposed within and coaxial with the barrel tube bore. The breech cap and the muzzle cap each longitudinally extend from a front end to a rear end and have through axial through bores. The breech cap is mounted to the barrel liner breech end portion and contacts the barrel tube breech end. The muzzle cap is mounted to the barrel liner muzzle end portion and contacts the barrel tube muzzle end. The inside diameter of the barrel tube bore is greater than the outside diameter of the barrel liner whereby the barrel tube does not contact the barrel liner.

The present invention discloses a personal protection device for multiple less-lethal ammunition options. The device is comprised of a lightweight carbon-composite forearm sleeve assembly having one or more externally mounted light-weight multi-layer composite barrels of various calibers for dispensing less-lethal ammunition at controlled muzzle velocities. In addition, Picatinny Rail attachment points are provided for mounting external tactical gear. The invention thus provides the user with multiple selectable less-lethal ammunition options in a single device while protecting the operating arm. Internally, the gauntlet contains a pistol grip with an electronic control system for selecting and firing individual less-lethal ammunition.

A projectile launching system can include a projectile launcher and a projectile. The projectile launcher can include at least one barrel, a projectile, a firing pin mechanism, an activator, and a power system. The barrel can extend along a longitudinal axis between first and second ends, with an exit port at the second end. The projectile can be positioned in the barrel and include primer, propellant, and a sub-projectile. The firing pin mechanism can be selectively project into the barrel to engage the primer, whereby the propellant is ignited and the projectile is launched out of the barrel. The activator can be engaged with the firing pin mechanism and engageable by a user to control the firing pin mechanism. The power system can rotate the barrel or the projectile as the firing pin mechanism is projecting into the barrel and engaging the primer of the projectile.

Weapon barrels are disclosed which offer improved thermal performance and rigidity with no, minimal or negative weight increase. In general the barrel comprises a barrel core surrounded by a lightweight, thermally conductive sleeve made from metal-matrix composite (MMC) materials, also referred to as metal-matrix material. The increased diameter of the sleeve improves the barrel's stiffness and the sleeve's thermal conductivity and distributes the heat more evenly along the barrel. Manufacturing and joining techniques are disclosed as well as materials and material combinations that allow the barrel to perform at high cadence over the whole temperature range the barrel is used. Hot spots may be reduced and more surface area can contribute to heat dissipation. The increased diameter also allows integration of phase changing and/or vibration dampening materials, which further enhance performance.

Provided are methods and related devices for disrupting an explosive device using a propellant driven disrupter (PDD) that propels a rounded projectile (RP) toward an explosive device. The RP travels along a linear trajectory and impacts the target, including a barrier portion of the explosive device. The impacting between the RP and barrier forms a composite projectile via a solid state weld between a portion of the barrier and the RP distal end, thereby minimizing or avoiding spall and fragment generation into the explosive device. The projectile traverses a penetration distance along the linear trajectory, or a defined-angle relative thereto, to disrupt the explosive device without unwanted explosive detonation.
