The Mk 14 Mod 0 EBR (Enhanced Battle Rifle) is a U.S. military-issue selective fire sniper rifle chambered for the 7.62x51mm NATO cartridge. It is a variant of the M14 battle rifle, built originally for use by units of the United States Naval Special Warfare Command, such as the United States Navy SEALs. The weapon takes the standard M14 action, replaces the 22" barrel with an 18" barrel and adds a chassis stock with a telescoping butt stock, a pistol grip, a gas lock front sight, bipod, Picatinny accessory rails at 12, 3, 6 & 9 o-clock, and a DC Vortex flash hider replaces the standard flash suppressor. A paddle-type bolt stop/release similar to that of the M4 carbine was used on the rifle. The SAGE EBR chassis stock is made up entirely of lightweight aircraft alloy. The MK14 Mod 0 and Mod 1 are made with the intention of carrying out both designated marksman and CQB roles in combat.
