This article is about the model featured in Halo: Reach. For the model introduced in Halo 4, see M395 DMR.
The M392 Designated Marksman Rifle (DMR), formally Designated Marksman Rifle, Caliber 7.62 mm, M392, is a gas-operated bullpup rifle used by the United Nations Space Command. It is manufactured by Misriah Armory.
The M392 Designated Marksman Rifle was adopted into service in 2512, serving as the primary weapon of Army squad marksmen and reconnaissance units. The weapon also found use with the Marine Corps and Air Force combat rescue teams during the Insurrection and much of the Human-Covenant War. However, it was largely superseded by the BR55 battle rifle, especially following the introduction of the BR55's heavy-barreled variant in 2548.
Nonetheless, due to its reliability and efficiency the M392 continued to see extensive use with the Army throughout the remainder of the conflict. In the wake of the Covenant War the M392 is still in service with the Army as well as Marine Corps reserve units. However, use of the newer, sturdier M395 DMR (designed for use by Spartan operators) is more widespread.
Design and operation
The M392 is an air-cooled, magazine-fed, gas-operated select-fire bullpup rifle that fires 7.62×51mm ammunition. It accepts a fifteen-round detachable box magazine similar. The weapon has a mounted EVOS-D optic capable of 3× magnification. The weapon's fire selector switch (located above the grip) has three settings: SAFE, FIRE, and AUTO. The magazine release button is located directly above the magazine well, behind the trigger. The weapon has an ejection port on either side so it may be used comfortably by a right- or left-handed shooter.
The M392 DMR's intended battlefield application is to provide accurate fire at medium to long range. It is intended for experienced operators with proficient skill in shot placement and controlled firing since the recoil from multiple shots must be controlled to effectively deliver maximum damage to the target and to ensure that the target is neutralized at the fastest possible rate.
In order to deliver hits to a target at medium-to-long ranges, a pause after each shot with the DMR is required to allow the reticule to contract to its smallest possible size. Immediately firing upon reacquisition of target maintains the maximum rate of accurate fire. While at close-to-medium range, it is only necessary to allow the reticule to shrink enough that it is roughly equal to the size of the target before firing again. At extremely close ranges, it is unnecessary to allow the reticule to contract at all, and it is most effective to fire the rifle as fast as possible.
In multiplayer, the M392 can kill a fully shielded Spartan in five shots, provided the last shot is to the head. A skillful marksman can eliminate a shielded enemy with ease. This makes the DMR one of the most versatile weapons in-game; it is much more powerful than the BR55. Compared with the M6G magnum, the DMR has a slower firing rate in exchange for higher accuracy and larger magazine capacity, however it shares almost the same amount of damage.
The DMR is a very precise weapon that fires hitscan projectiles, allowing it to engage targets well outside the range of other weapons. It also has considerable stopping power, making it effective against nearly all Covenant infantry, shielded or unshielded. The DMR is unparalleled in neutralizing unshielded enemies, as a single headshot is always fatal. This leads the M392 to be a weapon of choice against Covenant personnel that lack energy shielding such as Grunts, Jackals, Brutes, and Drones.
Despite its accuracy, precision, and power, the M392 has a few noteworthy drawbacks. To retain accuracy, the player must pace his/her fire to account for recoil, making the DMR have an effective fire rate only slightly faster than the sniper rifle. In addition, its magazine reserve (four, for a total of 60 rounds) is less than the sniper rifle's (five, for 20 rounds), meaning you have one less reload with the DMR. However, sniper ammo is much rarer than DMR ammo.
