The Mk 47 Grenade Machine Gun, also known as the Advanced Lightweight Grenade Launcher (ALGL) System and sold commercially as the Striker 40, is a reliable, portable 40mm grenade weapon system suited for mobile, tactical combat soldier units. The weapon integrates sensing, targeting and computer-programming technology. The Mk 47 low-recoil weapon system is 100 pounds lighter than the Mk 19 Mod 3 at 39.6 Pounds versus 140 pounds. It features quick detach barrel for ease of transport. It fires standard NATO 40x53mm linked grenades, including programmable airburst ammunition. The Mk 47 fires from an advanced lightweight tripod, and universal vehicle mount.

It achieves a 90 percent hit rate on the first round. Some of the weapon's features include a lightweight video-sighting system, laser range finder, and electronic elevation mechanism. Produced by Raytheon, the Mk 47's sophisticated Lightweight Video Sight (LVS) fire control system utilizes laser rangefinding, image intensified night vision, and ballistic computer technology to assist soldiers in the detection, recognition and first-round engagement of target threats. he laser range finder that provide a fire solution for day/night operations in all weather.

General Dynamics Armament and Technical Products, previously General Dynamics Armament Systems (which had subsumed the weapon's original developer, Saco Defense), was the system integrator for the Striker 40 ALGL System, the first major advancement in crew-served weapon systems since the end of World War II. The Mk 47's advancements were made possible by advanced sensing, targeting and computer-programming technology. The Mk 47 ALGL was a lightweight, portable, 40mm grenade machine gun with an advance sight and fire control system that combine to give a gunner a high probability of first round target hits. It would provide NATO forces with a decisive technological advantage over enemy forces equipped with older crew-served weapons.
