How to Mount a 37mm Launcher

Launcher tubes were first developed for use by the military. Designed to be used with M-16 rifles, the launcher was used to fire a variety of projectiles in a combat situation. The 37mm launcher tube that is available for civilian purchase is designed to be mounted to standard accessory rails on the bottom of an AR-15 forearm. The 37mm launcher will fire firework, smoke, signal and noisemaker projectile rounds.
