Paintball marker with advanced gas release mechanism

A projectile launching device for launching projectiles, comprising:

• a main body including a breech and a feed port configured for accommodating and launching projectiles;
• a barrel connected to the main body, the barrel having a front portion and a rear portion, the rear portion of the barrel being connected to the breech, the front portion of the barrel being open so that a projectile may be launched from the barrel;
• a valve for controlling a compressed air supply for launching projectiles from the barrel;
• the valve being movable between an open position and a closed position;
• an actuator mounted within the body having a mass and a speed profile, the actuator positioned and configured to provide a force based on the mass and speed profile to move the valve from the closed position to the open position;
• a force control member positioned between the actuator and the valve such that the actuator contacts the force control member and then the force control member contacts the valve to provide force translation and control that allows the force acting on the valve to be manipulated completely independently of the speed profile and mass of the actuator.
