This series of rubber ball grenade features two major innovations making it the most user friendly and effective grenade of its type available today. User friendly because it is less likely to leak. This unit incorporates integrally molded membranes over the ports and does not rely on the pressure sensitive label to provide the seal. This design provides for a rugged unit that withstands the rigors of field deployment. Most importantly, it means clean and uncontaminated hands after handling. Effective because our Jet-Lite ignition system (patent pending) provides for virtually instant maximum output under pressure. These grenades will deliver and disseminate irritant very rapidly while skittering on paved surfaces. They will even ignite and continue to deliver irritant submerged in water. OPERATION: The grenades can be launched by hand or from most 12ga shotguns by using an appropriate launching adapter and launching cartridge. Upon release the safety lever separates and initiates the Model 201 precision delay fuze, which in turn initiates the Jet-Lite ignition system after a 1.5 second delay. Pressure from the ignition system ruptures the membranes over the ports, providing a path for smoke emission. SPECIFICATIONS: Diameter: 79mm (3.1"), Overall Height: 130mm (5.1"), Overall Weight: 360gm (12.7oz), Burn Time: 15-20 seconds.
