Abstract
A grenade launcher and attachment for use on an infantry weapon, such as a rifle. The launcher fires grenades of the type which have a hollow tubular rear chamber slidably mounted on a guide rod and a piston head fitted into the bore of the chamber to seal an explosive charge therein and form an extensible explosion chamber. Locking elements for silently installing the grenade launcher without the use of complex tools are provided. Recoil buffering or compensation is provided to minimize the perceived recoil when grenades or other projectiles are launched from a shoulder held firing position. A detent is provided to secure projectiles on the guide tube until they are fired.
