Overview

The M249 is an air-cooled, belt-fed, automatic-only firearm that fires from an open bolt position. It can accept linked ammunition through the top-mounted feed tray, or M16 magazines through the side-mounted port. Linked ammunition can be fed from either a loose belt or from a plastic 200-round magazine clipped under the receiver. The SAW (Squad Automatic Weapon) features a built-in bipod and a tripod mounting lug for supported fire, and a quick-change barrel that helps prevent overheating during sustained fire.

The gun has an excellent reputation on reliability and firepower, and the latest reports on failures of M249 SAW weapons in Iraq are attributed to the age of the weapons used - most of the current issue M249s in US Army are more than 10 years old and quite worn out.

Usage

  • United States (M249) - the M249 has been in service with the US Army since 1984. In the USMC, the SAW is usually carried at the fire team level; that is, one member of a three- to five-man team carries this weapon. The SAW is also standard issue for a four- to five-man amphibious reconnaissance team.
  • United Kingdom (L108A1 (Minimi)/L110A1 (Minimi Para)) - recently, the British Army has equipped each four man fire team (2 per section) with the current variant of the Minimi Para. It is considered a fire support weapon between light support weapons and general purpose machine guns. They are usually fitted with the Common Weapon Sight (CWS) - an optical day and night sight.
  • Australia (F89) - the Australian Army uses a locally built version of the FN light machinegun. It is essentially the same, but fitted with a Picatinny rail and a 1.5x magnification optical sight. It also has a longer flash suppressor than the standard Minimi. Two F89s are carried in each nine-man infantry section. Small numbers of the Para Minimi are used by Australian paratroopers.
  • Canada (C9) - the original Canadian C9 is a standard factory Minimi with a steel tubular stock. The C9A1 comes fitted with a Picatinny rail on the feed cover and a 3.4x Elcan C79 scope. The C9A2 mid-life upgrade introduces a shorter barrel, camo green components, cloth ammo boxes (replacing plastic magazines), an M4-style collapsible stock, a folding pistol foregrip, and a standard-issue laser aiming module/device (LAM/LAD).
  • Israel (Minimi) - the Israeli Defence Forces were among the first to introduce the Minimi as a legitimate 5.56 mm SAW, and show its quality in combat. Limited numbers of Minimis were purchased in the early 1990s and saw combat in south Lebanon. The Minimi performed well and bought itself reputation, but in 1995 it was decided to purchase the IMI Negev, an Israeli manufactured 5.56 mm LMG, which fitted more to IDF requirements.
  • France (Minimi) - the Minimi is widely used by the French Armée de Terre.
  • Nepal (Minimi) - the Nepalese army uses 5,500 Minimi machineguns. The weapon delivery was endorsed on July 11, 2002 by the Belgian government.
  • Sweden (Ksp 90) - the armed forces of Sweden use the Minimi machine gun.

Variants

M249 Para - features a retractable stock and a shorter barrel. It was designed as a paratrooper weapon, although its compact dimensions make it desirable in any combat scenario.

M249 SPW - the Special Purpose Weapon has Picatinny rails mounted on the feed cover and forward grip, a short barrel and a Para-style retractable stock. Some features from the SAW and Para models were removed to save weight - these include the STANAG magazine port, the tripod mounting lug and the built-in bipod. The SPW was adopted by the US SOCOM under the designation Mk46 Mod 0.

Many US SAWs have been modified to carry SPW-style Picatinny rails on the feed cover. This allows them to mount commercial day and night optical sights like the M68 Aimpoint or low-magnification scopes. Additionally, some SAWs have fixed steel tubular stocks instead of the polymer stock pictured above.

All SAWs can mount the laser equipment needed to participate in a MILES combat simulation. This picture (http://en.wikipedia.org/wiki/Image:Fibua.jpg) shows an M249 fitted with MILES gear.

The weapon can also mount 3rd party suppressors. In particular, Gemtech manufactures suppressors designed to be mounted on NATO standard flash hiders, such as the one used by most variants of the M249. In reality however, this practice is discouraged since most suppressors overheat when subjected to sustained fire.
