High Quality Content by WIKIPEDIA articles! The Special Forces Combat Assault Rifle, or SCAR, is a modular rifle made by Fabrique Nationale de Herstal (FNH) for the U.S. Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consist of two main types. The SCAR-L, for light, is chambered in the 5.56x45mm NATO cartridge and the SCAR-H, for heavy, fires 7.62x51mm NATO. Both are available in Long Barrel and Close Quarters Combat variants. The FN SCAR system completed low rate initial production testing in June 2007. After some delays, the first rifles began being issued to operational units in April 2009, and a battalion of the US 75th Ranger Regiment will be the first large unit deployed into combat with 600 of the rifles in 2009.
