The M392 Designated Marksman Rifle (DMR), formally Designated Marksman Rifle, Caliber 7.62mm, M392,[6] is a gas-operated bullpup rifle used by the United Nations Space Command and Colonial Military Authority.[5][7] It is manufactured by Misriah Armory.[2][8]

Overview[edit]

Design details[edit]

The M392 is an air-cooled, magazine-fed, gas-operated select-fire bullpup rifle that fires 7.62×51mm ammunition.[2][5] It accepts a fifteen-round detachable box magazine. 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.[5] 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.[1][2][3][5][6]

The overall construction of the M392 is modular in nature, allowing it to serve as a versatile alternative to the predominant assault rifle and battle rifle lines used by the rest of the UNSC.

The M392 Designated Marksman Rifle was adopted into service in 2512, serving as the primary weapon of UNSC Army squad marksmen and reconnaissance units (presumably replacing the Insurrection-era M295 DMR). 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Force combat rescue teams during the Insurrection and much of the Human-Covenant War.[9][10] However, it was largely superseded by the BR55 battle rifle, especially following the introduction of the BR55's heavy-barreled variant in 2548.[2][5][6]

Nonetheless, due to its reliability and efficiency the M392 continued to see extensive use with the Army throughout the remainder of the c
