It is a modified and accurized version of the M14 rifle built and utilized solely by the United States Marine Corps (USMC). It is based on the current U.S. Marine Corps Designated Marksman Rifle (DMR), which it will replace.

The rifle is currently issued with match-grade M118LR 175-grain Long Range ammunition. The "basic" EMR (i.e., without telescopic sight, magazine, sling, basic issue items, cleaning gear, suppressor and bipod) weighs 13 pounds (5.9 kg) or less.

pecifications

There are several notable differences between the DMR and EMR.
*Stock: the metal stock is adjustable in length and in height to provide a more precise cheek weld. The pistol grip is modified for a better grip.
*Optics: The MIL-STD-1913 Picatinny rail allows for the use of any optic compatible with the rail; this includes a rather large variety of military scopes and imaging devices. The M8541 Scout Sniper Day Scope (SSDS), originally designed for the M40A3, and is issued with the rifle as a set.
*Bipod: A Harris S-L bipod is used on the USMC DMR, but a modified version is used on the EMR to be more durable.

Applications

The EMR is primarily used by a designated marksman. As a replacement for the DMR, the EMR fills the need for a lightweight, accurate weapon system utilizing a cartridge more powerful than the M16A4's standard 5.56x45mm NATO—the 7.62x51mm NATO. The EMR also sees use from Marine Scout Sniper when the mission requires rapid accurate fire. The EMR is also used by the Marine Corps Explosive Ordnance Disposal teams.
