The M393 Designated Marksman Rifle, more commonly known as the DMR, is a long-range infantry firearm and a successor to the M392 Designated Marksman Rifle.
Overview & Background
The M393 Designated Marksman Rifle is an air-cooled, gas-operated, magazine-fed, semi-automatic bullpup marksman's rifle equipped with a smart-linked, telescopic, rail-mounted 4x scope with an integrated ammunition counter. Unlike the previous M392 DMR, which was supplanted by the Battle Rifle as the UNSC's primary mid-range firearm, the M393 is a complete revision that served to bridge the medium-long range weapon gap between the Battle Rifle and the Sniper Rifle. The DMR fires 7.62×51mm NATO ammunition at a significantly high velocity, which outperform the Battle Rifle's low velocity rounds in two situations: draining a target's personal energy shielding, and eliminating targets from longer ranges. Additionally, the DMR's fifteen round detachable box magazine allows the weapon to last longer in combat without having to reload, while its lighter ammunition and more compact frame makes the DMR a more widely applicable and easier to carry/use long range alternative to the Sniper Rifle.
While the M393 DMR is distributed within the UNSC Marine Corps as a standard-issue rifleman's weapon, its unique mode of operation means that it is typically only used by marksmen trained in using the weapon. When fired, the weapon produces a significant amount of recoil that is absorbed by the weapon, which affects the weapon's accuracy a split-second after firing. This loss in accuracy is only noticeable if the user rapidly fires the weapon, making the DMR more effective when fired in a controlled manner with proper spacing between shots.
