摘要： An upper receiver for a firearm. The firearm includes a barrel extending forward of the upper receiver and a buttstock extending rearward of the upper receiver. The upper receiver includes an arcuate surface formed in a wall of the chamber. The arcuate surface changes direction of gases that are directed rearward in the chamber such that the gases are vented from the upper receiver in a non-rearward direction.

摘要： A charging handle includes a shaft, a front end that is operably coupled to a firearm bolt carrier, and a head that is located on an opposite end of the shaft from the front end. One or more ventilation features may be located in a first half of the length of the shaft proximate to the front end of the charging handle to prohibit exhaust that travels from the front end along the upper surface and/or side surfaces of the shaft from reaching the rear of the firearm and/or the head of the charging handle.

摘要： A heat dissipating and strength enhancing cover for a firearm gas tube includes a wire helix formed of closely adjacent coils having an inner diameter sized to closely fit over and in contact with an exterior surface of a gas tube. The wire of the gas tube cover may be made of a Beryllium-Copper alloy and have sufficient flexibility to accommodate at least one bend in the gas tube. The ends of the gas tube cover may be formed to a substantially flat surface that is substantially perpendicular to a longitudinal axis of the helix and may include caps covering first and second ends of the gas tube cover. The caps may prevent rotation of the cover when installed. The cover may extend substantially between a gas block and means for mounting a barrel when installed.

摘要： A firearm barrel assembly having a gun barrel with a muzzle opening on a distal end, a shroud coaxially surrounding at least a portion of the barrel, the shroud having a distal portion extending beyond the muzzle opening defining a shroud front region having a distal end portion, a proximal portion extending proximally from the muzzle opening defining an annular region between the barrel and shroud, the shroud front region and annular region in fluid communication with substantially no obstruction between the shroud front region and the annular region, and a front wall disposed at the distal end portion of the shroud. The wall has an opening to allow passage of a projectile fired from the firearm.

摘要： An evaporative barrel cooler for a firearm includes a firearm adapter having a mist nozzle, and a high pressure coolant reservoir attached to the firearm adapter with a flexible hose. The firearm adapter orients the nozzle inside a firearm chamber and aligned with the bore of a firearm barrel. The firearm adapter conforms to the interior of a firearm action and replaces a firearm bolt. The firearm adapter accesses the chamber through an open action port or through the bolt's raceway. The high pressure coolant reservoir may further include a hand pump attached to the reservoir for pressurizing the coolant. A coolant valve may be incorporated into the flexible hose to control the flow of coolant, whether it is water, alcohol, gunpowder or bullet metal solvent, or a nonflammable and nonreactive material.

摘要： A hand firearm with a casing in which the system is arranged and a valve leading from the inside of the casing to the outside which is so designed that an overpressure in the casing may be vented to the outside, in which a gas-permeable, heat conducting solid medium is arranged in the region of the valve in the flow path of the gas leaving via the valve in order to prevent any danger from hot gases being forced out of the weapon.
