Specifications

There are several notable differences between the basic M14 and the U.S. Marine Corps DMR.

  • Barrel: A 22-inch (560 mm) stainless steel, match grade barrel by either Krieger Barrels, Inc. or Rock Creek Barrels, Inc. (Mike Rock Barrels).
  • Stock: McMillan Tactical M2A fiberglass stock. This particular stock features a pistol grip and a buttstock with adjustable saddle cheekpiece.
  • Optics: The MIL-STD-1913 Picatinny rail built by GG&G Armament Arizona allows for the use of any optic compatible with the rail; this includes a rather large variety of military scopes and imaging devices. The most common scope used on the USMC DMR are TS-30.xx series day scopes, AN/PVS-10 or AN/PVS-17 night vision scopes, and Leupold Mark 4 or Unertl M40 10× fixed power scopes.
  • Muzzle device: Most USMC DMRs utilize the traditional M14 muzzle device, although since deployment in 2001, some DMRs are now equipped with the OPS, Inc. 2-port muzzle brake, which is threaded and collared to accept an OPS, Inc. 12th Model sound suppressor.
  • Bipod: A Harris S-L bipod is used on the USMC DMR.

Applications

The DMR, as its name suggests, is primarily used by a designated marksman. The DMR fills the need for a lightweight, accurate weapon system utilizing a cartridge more powerful than the M16A4's standard 5.56 × 45 mm NATO—the 7.62 × 51 mm NATO.
