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.

These EBRs are made with the intention of carrying out both designated marksman and close combat 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-inch (560 mm) barrel and lugged GI flash hider; it is not to be confused with the Mk 14 Mod 0 or Mod 1.

The creation of the Mk 14 Mod 0 EBR began in 2000 after a request by United States Navy SEALs for a more compact M14 battle rifle. In 2001, Mike Rock Rifle Barrels was the only rifle barrel maker asked by United States Special Operations Command to participate in a SOPMOD conference to create what would be the Mk 14 Mod 0 EBR, with details that include a collapsible stock that was requested for the new rifle and with an aluminum body with telescopic rails. Mike Rock collaborated with engineer Jim Ribordy to make the new rifle. Tests showed that their rifle was effective, but had excessive noise problems.

In 2003, Ron Smith and Smith Enterprise, Inc. created its own version of the M14 EBR (MK14 SEI), which used a medium heavy weight 18.0" barrel and was more widely favored than the rifle made by Rock and Ribordy. The Smith Enterprise-based MK14 was then used as a basis to eventually create the Mk 14 Mod 0 with Springfield Armory, Inc. being tasked to supply the necessary machinery needed to create the weapon in cooperation with the Naval Surface Warfare Center Crane Division.
