The United States Navy Mark 14 Enhanced Battle Rifle (EBR) is an American selective fire military rifle chambered for the 7.62x51mm NATO cartridge. It is a variant of the M14 battle rifle and was originally built for use with units of the United States Naval Special Warfare Command, such as the United States Navy SEALs.[6][7] 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 M14EBR-RI rifles per infantry squad for units deploying to Afghanistan. The M14EBR-RI has a standard weight 22.0" barrel and lugged GI flash hider; it is not to be confused with the MK14 Mod 0 or Mod 1.

The creation of the Mark 14 Mod 0 Enhanced Battle Rifle (EBR) began in 2000 after a request by United States Navy SEALs for the creation of a more compact M14 battle rifle.[8] In 2001, Mike Rock Rifle Barrels, Inc. 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 Mark 14 Mod 0 rifle, with details that include a collapsible stock that was requested for the new rifle and with aluminum body with telescopic rails. [2] Mike Rock collaborated with engineer Jim Ribordy to make the new rifle. Tests showed that their rifle was effective, but has excessive noise problems.[2]
In 2003, Ron Smith and Smith Enterprises Inc. created its own version of the M14 Enhanced Battle Rifle (MK14 Mod 0 type SEI),[9] which used a medium heavy weight 18.0" barrel and was more widely favored than the rifle made by Rock and Ribordy. The Smith Enterprises-based MK14 was then used as a basis to eventually create the Mark 14 Mod 0 with Springfield Armory, Inc. being tasked to supply the necessary machinery needed to create the weapon[2] in cooperation with the Naval Surface Warfare Center Crane Division.[10]
United States Navy SEALs were the first forces to be armed with the EBR in 2004, followed by the US Coast Guard.[2] The United States Army is also being armed with the M14EBR-RI, being created and updated by the Weapons Product Support Integration Directorate of the TACOM Life Cycle Management Command at the Keith L. Ware Test Facility in Rock Island Arsenal, Illinois;[11][12] having fielded approximately 5,000 units by mid-2010.[13] United States Marine Corps units were also considering the EBR,[14] but wound up instead developing the M39 Enhanced Marksman Rifle.
The weapon takes the standard M14 action and replaces the standard barrel with an 18.0" barrel, The barreled action is then bolted into a telescoping chassis stock system,[6] with a pistol grip,[11] a different front sight, Harris bipod,[11] four Picatinny accessory rails (which surround the barrel),[6][10][14] and a more effective flash hider in place of the standard lugged USGI flash suppressor.[15] A paddle-type bolt stop similar to that of the M4 carbine is used on the rifle.[10] The EBR chassis system stock is made up entirely of lightweight aircraft alloy.[16]
A Kydex hand guard and M68 CCO are also added as standard external accessories, though they are almost always replaced with a vertical foregrip and magnifying scope for better handling and for use in a designated marksman role. A Wind Talker suppressor can be mounted on the DC Vortex flash hider,[17] though the U.S. military did not adopt one to active service.[2]
Sage International had some involvement in the decision of whether to invest approximately $120,000 in an injection mold incorporating into the design the rail attachments or machine the replacement stock from a solid billet of aluminum with the former being selected, which was then shown at the SHOT Show in Orlando in 2003.[18]
Several configurations are allowed on the Mark 14 Mod 0 rifle, among them include the attachment of the AN/PVS-4 night vision scope.[19] Others had included the capability of adding two different scopes/sights on the Picatinny rails, for more precision or zoom level.[19]
While the Naval Surface Warfare Center Crane Division creates the military Mark 14 Mod 0 and MK14 Mod 1 rifles, Sage International was contracted to only do the weapon's chassis-type stock.[4]
The civilian version created by Smith Enterprise Inc. is also known as the MK14 Mod 0 type SEI [20] The Sage EBR chassis stock is available in a carbine variant known as the M14ALCS/CV.[21] The carbine variant is also known as the MK14 Mod 1. [18] The MK14 SEI Mod 1.[22]
Others include Fulton Armory,[23] firing in semi-automatic mode instead of fully automatic.[24]
Troy Industries has created a replica of the EBR's modular system made by Naval Surface Warfare Center Crane Division called the Troy Modular Chassis System, which can be used by mounting any functioning M1A or M14 rifle on the MCS.[25] Ferfrans has created their version of the Mark 14 Mod 0 called the Ferfrans Enhanced Battle Rifle.[26]
Users have praised the weapon to be user friendly due to it being ergonomical, having low recoil and an effective low-cost platform to change all "surplus M14s into modern battle rifles", as well as having the option of various optics and accessories left to the user's preference.[14]
