 * The M79 "Thumper" was the result of Project Niblick, which was an effort to increase the firepower of the standard infantryman. It used a simple design and fired many types of rounds.
 * The China Lake Grenade Launcher was manufactured by the American China Lake Naval Weapons Center for the Navy SEALs at the request of a faster-firing grenade launcher.
 * The similarities in appearance are due to the fact that both use the same recoil management system, which comprised of a horizontal and unagled recoil pattern.
