Abstract
A blaster for shooting projectiles that includes a housing that defines a housing interior, and a variable velocity barrel assembly positioned in the housing interior. The variable velocity barrel assembly includes a barrel that defines a barrel axis and a barrel interior. The barrel includes an exit opening at a distal end thereof. At least a first opening communicates the barrel interior with an exterior of the barrel. The first opening is defined through a side wall of the barrel. A slider member that includes a cylindrical portion that surrounds the barrel is movable axially along the barrel between a maximum velocity position where the cylindrical portion covers the first opening and a minimum velocity position where the slider member does not cover the first opening.
