M 249 SAW

• Features The Squad Automatic Weapon (SAW), or
  5.56mm M249 is an individually portable, gas
  operated, magazine or disintegrating metallic
  link-belt fed, light machine gun with fixed
  headspace and quick change barrel feature. The
  M249 engages point targets out to 800 meters,
  firing the improved NATO standard 5.56mm
  cartridge.The SAW forms the basis of firepower
  for the fire team. The gunner has the option of
  using 30-round M16 magazines or linked ammunition
  from pre-loaded 200-round plastic magazines. The
  gunner's basic load is 600 rounds of linked
  ammunition.

M 249 SAW

• Background The SAW was developed through an
  initially Army-led research and development
  effort and eventually a Joint NDO program in the
  late 1970s/early 1980s to restore sustained and
  accurate automatic weapons fire to the fire team
  and squad. When actually fielded in the
  mid-1980s, the SAW was issued as a one-for-one
  replacement for the designated "automatic rifle"
  (M16A1) in the Fire Team. In this regard, the SAW
  filled the void created by the retirement of the
  Browning Automatic Rifle (BAR) during the 1950s
  because interim automatic weapons (e.g.
  M-14E2/M16A1) had failed as viable "base of fire"
  weapons.

M 249 SAW

• Background Cont. -
• Early in the SAW's fielding, the Army identified
  the need for a Product Improvement Program (PIP)
  to enhance the weapon. This effort resulted in a
  "PIP kit" which modifies the barrel, handguard,
  stock, pistol grip, buffer, and sights.
• The M249 machine gun is an ideal complementary
  weapon system for the infantry squad platoon. It
  is light enough to be carried and operated by one
  man, and can be fired from the hip in an assault,
  even when loaded with a 200-round ammunition box.
  The barrel change facility ensures that it can
  continue to fire for long periods. The US Army
  has conducted strenuous trials on the M249 MG,
  showing that this weapon has a reliability factor
  that is well above that of most other small arms
  weapon systems. Today, the US Army and Marine
  Corps utilize the license-produced M249 SAW.
