Ring airfoil projectile

Ring airfoil projectile (RAP) is designed as an incapacitant. The original design used kinetic and tear gas projectiles for use in the M234 Riot Control Launcher. The design of the RAP is an aerodynamic, circular-tubed-shaped munition that discharges tear gas on impact and/or uses blunt force trauma to subdue or deter a subject. The main advantage to using RAPs is that their design does not allow them be thrown back by rioters with any real effect.
