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.

In combination with an infantry weapon having a bayonet lug mounted near the distal end of its barrel and projecting receiver bolts positioned at the forward portion of the rifle receiver on opposite sides thereof, a projectile launcher for firing individual projectile rounds comprising, in combination: (a) a launcher body; (b) a pair of hooklike projecting elements attached at one end of the launcher body for engagement of the projecting bolts on the rifle receiver to permit purely pivotal movement of the launcher body about the projecting bolts relative to the barrel of the infantry weapon and removal from the rifle without the use of tools when the launcher body is pivoted about the receiver bolts; (c) a projecting tongue portion attached to the first end of the launcher and having locking means disposed thereon for engagement with the bayonet lug of the infantry weapon when the launcher body is pivoted about the receiver bolts into a position with the launcher body parallel to the barrel of the weapon; (d) an opening in the projecting tongue portion positioned to receive the bayonet lug when the launcher body is pivoted into position parallel to the barrel; and (e) pivotally movable engaging means including actuating arms and clamping jaws mounted on both sides of the opening constructed and arranged when actuated to open the jaws to allow insertion of the bayonet lug along an axis perpendicular to the longitudinal axis of the barrel into the opening and when not actuated to engage the step of the bayonet lug and resist pivotal movement of the launcher body away from parallel alignment with the barrel of the infantry weapon by interference with the widened step of the bayonet lug with the engaging means.
