ABSTRACT:
Disclosed is a dual purpose projectile and weapon combination whereby an individual can select one of two different projectile configurations and consequent performance characteristics when firing a single projectile from the weapon. In one projectile configuration, the projectile has a conventional bullet-shaped body and a frontal area corresponding to its caliber. In the other projectile configuration, the projectile is configured to provide a low velocity short-range large frontal area missile having minimal penetration with high impact to obtain a disabling effect. The weapon has a barrel ring attachment which is rotatable to select the desired projectile configuration. The attachment includes a cutter selectively extensible into and retractable from the path of movement of the projectile through the barrel. The attachment also vents the weapon barrel to relieve pressure in the cutter area and this functions as a muzzle brake thereby reducing the velocity of the projectile when fired in its second configuration.
