I've been reading "Whattaya Mean I Can't Kill 'Em?" by Rad Miller Jr. He was a member of SEAL team 1 in Vietnam. Very good read. He was talking about the weapons the teams liked to carry and mentioned the Stoner Weapons System, which I had never heard of:
"We are introduced to the Stoner Weapons System, which is a light machine gun using the M-16 5.56mm round... The ammo is used in 150-round linked belts, which feed from a round metal drum under the barrel. SEALs usually remove the shoulder stock, which leaves the Stoner with just a pistol grip, although a few guys keep the stock out of personal preference. A short barrel is installed and a shoulder sling is mounted on the weapon that allows it to be carried hanging horizontally in a ready to fire position. Lightweight, mechanically reliable, and with a firing rate of 700-900 rounds per minute, it will lay down a huge volume of fire, perfect for a small squad pretending to be much more numerous than it really is. All of us really like the Stoner and it will be our first choice for usage in Vietnam."
