The HK69A1 is a 40 mm grenade launcher developed and produced by the German arms manufacturer Heckler & Koch (H&K). The grenade launcher is a single-shot, shoulder-fired, breech-loaded weapon that fires a projectile using the High-Low System. The main component is the frame that contains and integrates all of the weapon’s mechanisms and assemblies. The weapon features a rifled barrel, which is hinged at the front and tilted upward ("break action") for loading and removing spent shell casings.
