Projectile launch assembly and method

A method for launching a projectile, the method comprising the steps of:

• providing a projectile launch assembly comprising:
• a launch tube having distal and proximal ends and an inwardly extending dimple therebetween;
• a receiver disposed on the distal end of the launch tube, the receiver having connector structure at a distal end thereof for connection to a projectile;
• an energy absorbing plug having a proximal end portion adjacent the dimple and a body portion extending distally;
• and
• an energy transfer piston adjacent the plug and having a proximal end configured complementarily to the plug and having a distal end configured complementarily to a proximal end of the receiver;
• manipulating the receiver connector structure to connect a selected projectile to the receiver;
• sliding the launch tube onto a muzzle portion of a firearm until a distal end of the muzzle portion engages the dimple;
• and
• firing the firearm;
• wherein a bullet leaving the firearm muzzle is absorbed by the plug which is thereby moved with the piston distally in the tube;
• wherein the piston engages the receiver to propel the launch assembly and the projectile from the firearm muzzle;
• and
• wherein the receiver connector structure comprises a threaded axial recess in the distal end of the receiver;
• and
• the step of connecting the projectile to the receiver comprises threadedly engaging a threaded shaft of the selected projectile with the threaded axial recess of the receiver.
