The M39 Enhanced Marksman Rifle (EMR; formally Rifle, Caliber 7.62 mm, M39 Enhanced Marksman Rifle; NSN 1005-01-553-5196) is a semi-automatic, gas-operated designated marksman rifle chambered for the 7.62×51mm NATO cartridge. It is a modified and accurized version of the M14 rifle used by the United States military, similar to the Mk 14 Enhanced Battle Rifle. It is based on the United States Marine Corps Designated Marksman Rifle (DMR), which it replaced. It is manufactured by Sage International and maintained by the USMC's Precision Weapons Section.[1]
The rifle is currently issued with match-grade M118LR 175-grain long range ammunition. The "basic" EMR (without telescopic sight, magazine, sling, basic issue items, cleaning gear, suppressor and bipod) weighs 13 pounds (5.9 kg) or less.
