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.〔(Modern Firearm's M14 Page. ) Retrieved on September 23, 2008.〕〔(Navy SEALs to get new rifles. ) Retrieved on September 23, 2008.〕 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. ==History== The creation of the Mk 14 Mod 0 Enhanced Battle Rifle (EBR) began in 2000 after a request by United States Navy SEALs for a more compact M14 battle rifle.〔(The History and Development of the SAGE M14ALCS Enhanced Battle Rifle (EBR) chassis stock system. ) Retrieved on September 23, 2008.〕 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 Mk 14 Mod 0 EBR, with details that include a collapsible stock that was requested for the new rifle and with aluminum body with telescopic rails. 〔(M14 Rifle History. ) Retrieved on September 24, 2008.〕 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 Enhanced Battle Rifle (MK14 SEI),〔(CRAZY HORSE US NAVY MK14 SEI MOD 0. ) Retrieved on October 5, 2008.〕 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.〔(New-era M14 Alleviates Reliability Issues. ) Retrieved on September 24, 2008.〕 United States Navy SEALs were the first forces to be armed with the EBR in 2004, followed by the U.S. Coast Guard.〔 The U.S. 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;〔(AMC Deputy Chief of Staff on Target with M14 Enhanced Battle Rifle. ) Retrieved on September 24, 2008.〕〔(Army's Chief of Staff visits Arsenal Island. ) Retrieved on September 24, 2008.〕 having fielded approximately 5,000 units by mid-2010. United States Marine Corps units were also considering the EBR,〔(M14 REBORN. ) Retrieved on September 25, 2008.〕 but wound up instead developing the M39 Enhanced Marksman Rifle. The rifle has seen limited service outside of the U.S., primarily with the Australian SASR in their Afghanistan deployment.〔http://www.dtic.mil/ndia/2012armaments/Wednesday13969Armstrong.pdf〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mk 14 Enhanced Battle Rifle」の詳細全文を読む スポンサード リンク
