WHEN THE 5.56MM M 16 (Armalite) rifle entered service during the Vietnam War it gave every man in the squad an automatic weapon, but with a maximum effective range of little more than 330yd (300m).

 

It was quickly realized, however, that both fire teams needed a weapon of greater all-round capability, but lighter than the contemporary 7.62mm M60 and one which used the same ammunition as the riflemen. This gave rise to a US Army requirement for a 5.56mm Squad Automatic Weapon (SAW), with the US Marine Corps joining the program later.

 

After considering all suitable weapons in the Western world, the US forces selected a "product improved" development of the Belgian Fabrique Nationale's (FN) "Minimi" which was placed in production as the M249, with initial supplies coming from the FN factory in Herstal, although a US line was subsequently established.

 

The product improvements in the US version include minor changes to the barrel, buffer, handguard, pistol grip, stock and sights.
