The M39 Enhanced Marksman Rifle (EMR, NSN 1005-01-553-5196; more formally the Rifle, 7.62 MM, M39 Enhanced Marksman Rifle (EMR)) is a semi-automatic, gas-operated rifle chambered for the 7.62x51mm NATO cartridge. 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 United States 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.

It has a resemblance to the Mk 14 Mod 0 Enhanced Battle Rifle.

Specifications

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, is issued with the rifle as a set.
• Bipod: A Harris S-L bipod is used on the USMC DMR, but a modified version designed to be more durable is used on the EMR.

Applications

A civilian peers through the scope of an EMR

The EMR is primarily used by a designated marksman, to provide precision fire for units that do not rate a Scout Sniper. 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 is also used by Marine Scout Snipers when the mission requires rapid accurate fire and by Marine Corps Explosive Ordnance Disposal teams.
