The Mk 14 Enhanced Battle Rifle (EBR) is an American selective fire military designated marksman rifle chambered for the 7.62×51mm NATO cartridge. It is a variant of the M14 battle rifle and was originally built for use with units of the United States Special Operations Command, such as the United States Navy SEALs, Delta Force, and task specific ODA units.
The EBRs are made with the intention of carrying out both designated marksman and CQB roles in combat. Since 2010, the U.S. Army has made available two M14 EBR-RI rifles per infantry platoon for units deploying to Afghanistan. The M14 EBR-RI has a standard weight 22.0" barrel and lugged GI flash hider; it is not to be confused with the Mk 14 Mod 0 or Mod 1.
