SCAR-Light

Developer: FNH USA (USA)
Caliber: 5.56mm
Features: More accurate and less prone to jamming than the standard-issue M16 and M4 rifles, the SCAR uses quick-change barrels that can be swapped using a minimal number of tools.
Progress: The manufacturer had initially expected the weapon to be deployed in 2006, but after a limited production run last year, there's hope for the SCAR.

The effort to replace the M-16 rifle, as well as its more compact variant, the M4, has been a long, epic and largely tragic tale. One attempt would have created a modular weapon system, called the Objective Individual Combat Weapon (OICW), with an integrated grenade launcher and laser-rangefinder. That all-in-one system was scrapped because of excessive weight, and subsequent attempts to salvage the core of that weapon—the XM8 assault rifle—have also failed, highlighting some of the worst aspects of the weapons procurement process.

Fed up with the rest of military's inability to replace the M-16 and M4, and apparently uninterested in an OICW-type multipurpose weapon, the Special Operations Command (SOCOM) held a competition for a new assault rifle, to be deployed with special forces personnel. Having passed muster as a more accurate and reliable weapon than the M4, FNH USA landed the contract with its FN SCAR, which comes in two calibers—5.56 for the SCAR-Light, and 7.62 for the SCAR-Heavy. The weapon also meets SOCOM's requirements for quick changes in the field. Within a few minutes, a SCAR-Light's 18-in.-long, precision-fire barrel can be replaced with a standard-length 14-in. barrel, or a shorter, 10-in. barrel for use in cramped, urban environments. Although the SCAR-Light is likely to be more common than the more powerful SCAR-Heavy, the two weapons share 99 percent of the same parts, making field repairs easier and streamlining the overall logistics.
