1. A toy projectile launcher, comprising:
a plurality of projectile holders, each projectile holder adapted to hold a projectile;
a cocking slide that is adapted to be moved forward and backward;
a launch barrel;
a housing;
an air piston assembly disposed within the housing, the air piston assembly including an air piston barrel having an air nozzle disposed on a front portion thereof, a plunger element, and a compression spring,
wherein the launch barrel and the air piston assembly are each coupled to the cocking slide,
wherein, when the cocking slide is moved backward from a forward position to a backward position:
the air piston barrel moves backward and pushes the plunger element to compress the compression spring against a rear wall of the housing; and
the launch barrel is moved forward away from a front portion of a first projectile holder in the plurality of projectile holders, and
wherein, when the cocking slide is moved forward from the backward position to the forward position:
the air nozzle moves forward to form an airtight seal between the air piston barrel and a rear portion of the first projectile holder; and
the launch barrel is moved backward toward the front portion of the first projectile holder to form an airtight seal between the front portion of the first projectile holder and a rear portion of the launch barrel.
