1. A toy projectile launcher comprising:
a housing;
an air piston assembly, the air piston assembly including an air piston barrel, a plunger element, a first compression spring, and a front air nozzle;
a cocking slide coupled to the air piston barrel;
a launch barrel; and
a storage belt including a plurality of projectile holders, wherein each projectile holder is adapted to contain a projectile,
wherein, when the cocking slide is moved from a forward position to a backward position in a first priming step and, after the first priming step, from the backward position to the forward position in a second priming step:
an internal air chamber is formed between a front portion of the air piston barrel and the plunger element;
an advancement mechanism of the storage belt advances a next projectile holder into a firing position in front of the front air nozzle; and
the front air nozzle of the air piston assembly pushes forward on a rear portion of the next projectile holder, forming an airtight seal between the air piston barrel and the rear portion of the next projectile holder,
wherein an airtight seal is formed between a front portion of the next projectile holder and a rear portion of the launch barrel, and an airtight seal is formed between the air piston barrel and the rear portion of the launch barrel.
