These projectiles were developed specifically for 40mm grenade launchers such as the U.S. M203 and our TGL-1. The cartridge case fully chambers in such launchers, eliminating the possibility of the cartridge slipping past the extractor, as may occur with undersized cartridges. The undercut at the cartridge base further ensures reliable extraction after every shot. These are true 40mm rounds. They will not chamber in 37/38mm launchers. These rounds are available in CN tear agent, CS riot control agent, and white smoke for screening and tactical purposes. OPERATION: The round can be launched from a U.S. M203 or similar launcher such as our TGL-1 or M79. Firing the cartridge initiates the projectile. Smoke is emitted from ports at both ends of the projectile SPECIFICATIONS: Weight 235gm (8.3 ounces) Overall Length 4.8" (122mm) Effective Range 110 yds (100m)
