Stoner 63
Even very early on in its development stage, a small number of weapons were hurriedly put into service with the U.S. Navy SEALs deployed to Southeast Asia. During 1967, the Stoner 63 was tested by Company L (Lima Company), 3rd Battalion, 1st Marine Regiment, 1st Marine Division. In 1967, the Dutch firm NWM (Nederlandsche Wapen-en Munitiefabriek) De Kruithoorn N.V. of 's-Hertogenbosch acquired the rights to sell the weapon worldwide with the exception of the United States, Canada and Mexico. NWM assembled several prototypes but the company failed to sell the weapon. In 1970, the U.S. Army issued it to Army Special Force units. However, due to its complexity and high maintenance requirements, the weapon was rejected, and the project was dropped in 1971. That same year, Cadillac Gage ceased all production of the Stoner 63. Around 4,000 63 and 63A units were built in total. By the late 1980s the Stoner 63 was completely phased out in favor of the new M249 SAW, and most of the remaining guns were destroyed.
