Abstract: The invention relates to systems, methods and devices for controlling the dispersion of shot or other projectiles fired from a weapon such as a shotgun. Embodiments according to the invention employ an inner cylindrical chamber that is divided at a median transverse plane into forward and rear sections. The rear section of the chamber tapers toward the median transverse plane and includes a number of radial vents that open into an outer chamber that provides one or more gas bypass channels into the forward section of the tubular chamber. Alternatively, channels function as unitary vents and outer chamber to provide for a gas bypass. The forward section tapers toward a forward muzzle opening. When a multiple projectile load/wad is fired from the weapon, expanding gas is sealed behind the load until it has advanced past the radial vents at which point, gas is allowed to expand into the outer chamber resulting in a momentary pressure drop and reduced propulsion force behind the wad/load.

Abstract: This disclosure relates generally to cartridges for use in projectile-launching devices, such as ammunition cartridges, flare cartridges, and the like, including components of the cartridges, and methods for their manufacture.

Abstract: A pneumatic paintball marker has, for example, a sleeve that controls the passage of air through the longitudinal barrel or opening within the marker. By sequentially filling separate chambers defined within the opening and the sleeve, the sleeve is able to translate axially through the opening in a sequential manner. When the sleeve is in a forward position, air is caused to be released through the barrel, propelling the paintball. A sear member engages the sleeve and prevents it from inadvertently moving to a forward position. Air filling the chambers returns the sleeve to the loading position.

Abstract: Embodiments disclosed herein include systems and methods for regulating pneumatic gas propulsion. More specifically, some embodiments include a first spring that exerts a spring force, where the spring set point increases as the first spring is compressed. Similarly, some embodiments include a piston that is in physical communication with the first spring and a valve. The valve mechanism may receive the gas, where upon the gas being received by the valve mechanism at a pressure that meets the spring set point, the gas causes the piston to move in the longitudinal direction. Further, movement of the piston creates a cylinder space between the piston and the valve mechanism, where a volume of the cylinder space is defined by a position of the piston. The pressure causes the piston to compress the first spring until an equilibrium exists between the gas force and the spring force.
