How Do You Make A Grenade Launcher?
Most military grenade launchers are portable, and they can be single-shot or repeating. When used in combat, they’re often mounted under the barrels of military-style rifles. Portable launchers can fire not only grenades, but tear gas or incendiary devices that burn very brightly for illumination. For a low-tech twist, use a bow, arrow and shotgun shells to construct a perfectly functional grenade launcher. Step 1 Unscrew or remove the ferrule from around the arrow. Fill the arrow head with gun powder. Step 2 Put glue on the shotshell primer and press it into the opening formerly occupied by the ferrule. Glue the BB onto the primer. Step 3 Use the bow to shoot the arrow at an appropriate target. Typically, grenade launchers fire weapons greater distances, more accurately and faster than a person could throw by hand.
