Initially marketed towards the United State Marine Corps, the design was modified to fire flare rounds and the larger 40x53mm grenades used in automatic grenade launchers like the Mk 19. In 2009, it was reported that Airtronic USA (a company also known for manufacturing modernised RPG-7s under license from Bazalt) has started manufacture of the China Lake launcher and a modernised model with a retractable M4-type stock, pistol grip and Picatinny rails. Only four complete original weapons are thought to exist one at the UDT/SEAL Museum, one in a Vietnamese war museum, one in the hands of the ATF Technologies branch, and the last by Brian Fauci of Canal Side Guns, who make a knock-off of the weapon called "The Ultimate M79." The weapon was used in limited numbers by US Navy SEAL Teams, Marine Force Recon, and the 5th Special Forces Group. The weapon is essentially a pump-action M79 Grenade Launcher with a 3-round tubular magazine added under the barrel.

The China Lake Launcher was a prototype pump-action grenade launcher developed in the 1960s by the Naval Air Weapons Station China Lake.
