Breech loaded soft projectile blow gun

A blow gun for launching soft projectiles. The blow gun includes an action sleeve which is wrapped around and attached to a receiver. Soft projectiles, such as marshmallows, may be loaded into the breech of the blow gun by rotating the action sleeve approximately a quarter of a turn around the receiver. When rotated in this manner, a loading port in the action sleeve aligns with a corresponding loading port on the receiver, thus exposing the hollow interior of the receiver. A barrel is attached to one end of the receiver so that the hollow interior of the barrel and the hollow interior of the receiver are aligned. A muzzle brake extends beyond the barrel and has a plurality of brake vents to prevent the accidental inhalation of projectiles when inhaling on the muzzle end of the blow gun. The blow gun may be fired by blowing into a blow tube which is fluidly connected with the receiver.
