摘要： A projectile launcher includes a barrel, a high pressure chamber included within the barrel, and a low pressure area included within the barrel and substantially surrounding the high pressure chamber. The high pressure chamber includes an inner cavity and multiple vent holes connecting the inner cavity to the low pressure area so that high pressure gases generated in the inner cavity by a pressure cartridge can pass from the inner cavity to the low pressure area and propel a round (or projectile) out of the launcher.

摘要： A barrel and a barrel extension for being coupled to a firearm. The barrel extension can be threadedly engaged with a proximal end of the barrel. A chamber of the firearm can extend in at least the proximal end of the barrel. One or more channels can be formed in the exterior surface of the proximal end of the barrel and/or the interior surface of the barrel extension for providing fluid communication from the chamber to the forward end of the barrel extension between the barrel extension and the proximal end of the barrel for venting high pressure gases that may develop in the chamber.

摘要： A projectile launching device includes a primary tube having a primary passage for launching a projectile. In some embodiments, the projectile launching device further includes a secondary tube disposed about the primary tube and defining a secondary passage, and a flow apparatus in fluid communication with the secondary passage configured to move gas through the secondary passage. An opening is at the end of the secondary tube and is configured to allow gas to laminarly exit the secondary passage. In other embodiments, the projectile launching device further includes a flow apparatus in fluid communication with the primary passage configured to draw gas from the primary passage to provide at least a partial vacuum in the primary passage. The projectile launching device may provide increased range, accuracy, and velocity of the projectile, in addition to providing a reduced sound signature of the projectile launching device.

摘要： A cartridge gas port selector mechanism for a firearm barrel having a plurality of gas ports extending from the barrel bore and having a gas block with gas passages in communication with a gas tube. A selector valve member is movable within the gas block between an open condition permitting flow of cartridge gas from one or more ports of the firearm barrel to the cartridge gas passage and a closed condition blocking flow of cartridge gas from the barrel bore to the cartridge gas passage. A valve selector or actuator is connected with the valve member and is selectively moveable to position the valve member at the open condition or the closed condition to select the volume and timing of cartridge gas communication from the barrel bore to the gas energized autoloading mechanism of the firearm.

摘要： A firearm having a barrel and a whistle, wherein when the firearm is discharged air is forced through the whistle to cause a whistle sound. In one particular embodiment, the whistle comprises a barrel port, a channel, and a whistle port and wherein when the firearm is discharged a bullet traveling down the barrel forces air through the barrel port, the channel, and the whistle port to cause a whistle sound. In another embodiment, the whistle is associated with a firearm attachment and the firearm attachment is removably couplable to the firearm. In a further embodiment, the whistle is modifiable and modification of the whistle is configurable to eliminate or change the whistle sound. In a further embodiment, the whistle sound is associated with a signal that is transmitted to another device or central location for analysis, wherein the signal comprises a firearm identification or locational information.
