The upper receiver having a first end and a second end contains a bolt chamber. The second end of upper receiver and the second end of lower receiver are pivotally coupled whereby allowing the first end of upper receiver to be pivotally swung away from the first end of lower receiver.

Abstract: A projectile launching device such as a paintball gun capable of firing a paintball using a hammer is disclosed. The paintball gun, in one embodiment, includes a bolt, a valve, and a hammer wherein the bolt has an air channel and is able to move within a bolt chamber. The valve, which is situated in a firing control chamber arranged in parallel to the bolt chamber, controls pressurized gas. The hammer, in one aspect, includes a pivot hole capable of hosting a pivot pin which facilitates a swing motion for the hammer. When the hammer swings around the pivot hole, the hammer contacts the valve whereby a portion of the pressurized gas is release. The bolt further includes a hammer reset element which is able to reset the hammer to a ready for firing position during a launch process.

Abstract: A projectile launcher capable of optionally repositioning the bolt to a predefined position using a bolt carrier is disclosed. The launcher, in one aspect, includes a bolt, a striker, a bolt carrier, and a ramp. The bolt, in one example, is configured to be able to move within a bolt chamber. The striker having a striker reset hook is able to move in a direction parallel to a moving direction of the bolt. The bolt carrier, having a fastener, a flexible latch, and a bolt repositioning latch, is attached to the bolt via the fastener. The flexible latch is able to latch to the striker reset hook for resetting the striker during a process of launching a projectile. The ramp facilitates disconnecting the flexible latch from the striker reset hook when the flexible latch moves over the ramp.

Abstract: A projectile such as a paintball including a ball-shaped capsule and a round-shaped disc capable of facilitating accuracy of projectile travel direction is disclosed. The ball-shaped or substantial ball-shaped capsule, in one embodiment, having a head and a tail is able to store and deliver colored markers upon an impact between the projectile and an object. The round-shaped disc is positioned at a place so that allowing a portion of the round-shaped disc to extend above outer surface of the capsule. The disc is able to catch at least airflow when the projectile is launched. The round-shaped disc, in one example, uses the direction of the airflow to facilitate travel direction of the projectile.

Abstract: An ammunition magazine includes a first ammunition supply port (“ASP”), a second ASP, a first ammunition compartment, and a second ammunition compartment. The first ASP, in one embodiment, is able to couple to a coupling surface of the magazine and provide ammunition to a gun when the first ASP is connected to an ammunition loading port (“ALP”) of the gun. The second ASP is also coupled to the coupling surface of the magazine and provides ammunition to the gun when the second ASP is connected to the ALP of the gun. The first ammunition compartment occupies a first portion of ammunition capacity of the magazine and is able to arrange ammunition in a column formation. The second ammunition compartment occupies a second portion of ammunition capacity of the magazine and is able to arrange ammunition in a column formation.

Abstract: A paintball assembly capable of retaining a paintball in a loading chamber using a paintball catcher is disclosed. The paintball assembly includes a loading chamber, a detent, and a bolt. The loading chamber is coupled to a loading port to receive paintballs. In one embodiment, the detent includes a paintball catcher capable of catching the paintball as it is loaded into the loading chamber. In one example, the paintball catcher is a flexible paintball catcher extending into the loading chamber and is able to catch the paintball and hold it in a predefined position. When a trigger is pulled, the bolt pushes the paintball into a firing chamber while the paintball catcher releases the paintball.

Abstract: A bottom feed magazine of a paintball gun includes a housing for storing a plurality of paintballs. A circular tray is mounted to the housing. A hub is rotatable about a shaft within the circular tray at a center thereof. The circular tray and the hub together define an annular channel for receiving paintballs dropped therein from the housing. A plurality of arms is provided on the hub for driving the paintballs along the channel. A tube has an inlet end extending into the channel and an outlet end extending generally upwards to a top wall of the housing. When the central hub rotates, the paintballs in the channel are driven along the channel, into the inlet end and pushed up along the tube towards the outlet end.
