The MA5B assault rifle, or simply MA5B, is a standard-issue automatic rifle utilized widely by the United Nations Space Command, particularly the UNSC Marine Corps.[11] It is part of the Misriah Armory MA5 series.[2]
Overview[edit]

Design[edit]
The MA5B is a gas-operated automatic rifle chambered in the widespread 7.62x51mm cartridge, most often used with standard M118 FMJ-AP ammunition,[4] though also employed with shredder[7] and hollow-point rounds.[9] MA5Bs typically feed from 60-round detachable box magazines, but can also use smaller 36-round magazines.[4][5] Hollow-point rounds are loaded into magazines marked with red paint for rapid identification.[9] The weapon's automatic rate of fire is 15 rounds per second,[7] but it can be limited to semi-automatic[8] or 3-round burst via a fire selector to conserve ammunition and alter firing pattern.[9]
One significant aspect of the MA5B's design is its capacity for modification. Its barrel can be adapted for use with suppressors to combat the conspicuous report of the weapon's firing, making it especially suitable for stealth fighting;[12] SPARTAN-IIs made use of this attribute during the Battle of Sigma Octanus IV.[13] Early in the Human-Covenant War, SPARTAN-IIs also frequently employed MA5Bs with underslung M301 40mm launchers to fire HE grenades, notably during Operation: SILENT STORM[14] and the salvage operation on Netherop.[15]
The most characteristic part of the MA5B's architecture is the accentuated shroud situated atop the barrel, which houses the weapon's integrated computer and display. While most MA5 ICWS rifles feature this to some extent, it is most prominent on the MA5B. The magazine which feeds the rifle is inserted behind the thumbhole pistol grip in a bullpup configuration, another trait typical of the ICWS series. The charging handle is an inconspicuous rounded-off protrusion on the left of the weapon's body, and the ejection port is situated on the right. The weapon's horizontal foregrip plays host to a forward-facing flashlight, bearing a prominent green button on both flanks. The barrel of the MA5B lacks any form of muzzle device (unless fitted with a suppressor).[13] The finish of the weapon is a dull grey, with a darker grey color for the foregrip, pistol grip and stock.[16] As standard, the weapon and its cowling has no optical device or ironsight,[1] leaving the only evident means by which the weapon is aimed to be via HUD-based targeting reticle, such as that of MJOLNIR Mark V,[17] or by eyesight alone.[18]
Functionality[edit]
The MA5B, being a rifle, is held with the user's dominant hand on the main grip and their off-hand on the foregrip, with the stock stabilized against the shoulder. As is typical of human firearms, the MA5B is fired by the depression of a trigger positioned at the top of the main grip. When the trigger is pulled, the round in the weapon’s chamber is fired, and the weapon’s gas system harnesses some of the energy from the deflagrating propellant to cycle the bolt back into its open position.[6] As with most human weapons, the firing of the weapon creates a noticeable flash as the fiery gas of the propellant
