Tactical telescoping shotgun

摘要

A shotgun has a telescoping barrel made of concentric barrel sections slidably engaged together. These include at least an inner barrel section and an outer barrel section. A grip on the outer barrel section aids telescopic movement. A locking pin secures or releases the barrel sections. The barrel sections have protrusions that interfere with further outward movement once fully telescoped out. The grip may have a channel to permit a pistol grip to slide onto the grip. A second pistol grip may be connected to the trigger. The butt of the gun may slide out to make a shoulder rest. A butt plate is connected to a rod that slides into and out of the shotgun. The rod has teeth that engage a spring-loaded arm to secure the rod in an extended position. A compression or tension spring may bias the concentric barrel sections in an extended or shortened configuration.
