SCAR report by Cpl Ledanek and Rocky
Updated November 2007 with Movie by Dick Splash.

The Special Operations Forces Combat Assault Rifle (SCAR) Program was approved in Sept 2003, and completed in January 2004. The SCAR was the result of a search for a replacement for the aging M4A1 which had been in use since Vietnam, and battle tested through current conflicts both in Iraq and Afghanistan.

This task was given to FN Herstal, and developed and tested by Special Operation Forces personnel and all four branches of Armed Forces.

There are two versions of the SCAR:

  • Mark 16 SCAR Light (SCAR-L)
  • Mark 17 SCAR Heavy (SCAR-H)

Both version will replace each of the following 5 weapons usually requested by SOF:

  • M4A1
  • CQBR
  • Mark 12 Special Purpose Rifle (SPR)
  • Mark 14 (SR-25)
  • Mark 11 (SR-25)


Stock: Telescopes and folds. Depending on mission or need to conceal the weapon, and/or vehicle entries.
Cheeckpiece: Sloped and adjustable depending on Optical Scope mission.
Pistol Grip: Multiple adapters for big or small hands
Fire Control: safe---semi-auto----full auto, shorted or less of an arm compared to M4A1
Ambidextrous: All controls are available on both sides, reducing need for conversion kits.
Cyclic rates: 600-650 rounds per minutes vs M41's 900 rounds per minute, giving more control. On semi-auto, controlled burst shots about 3-5 rounds or a single shot.
Gas System: gas is driven to the rear and vented and released through a cam. This is suppose to reduce the fouling or build up, also making the SCAR-L easier to clean. Less time maintaining the weapon is always a bonus!
Rail System: Monolith MIL-STD 1913 Rail system. The rear and front sight post can be folded to give a unobstructed view for whatever optical sight is attached to the rail system.
Easy mounting of optical sights, such as the adopted AN/PVS-22 Universal Night Sight.
Also adaptable to any SOPMOD components required for whatever mission.
Barrel: Quick change depending on mission profile. Can be change in a minute by removing two bolts.
