The BR75 Service Rifle[5] is a battle rifle used by the UNSC,[2] manufactured by Misriah Armory in Eos Chasma.[6]

Overview[edit]

Design details[edit]

In appearance, the BR75 bears great similarity to the BR55 battle rifle. It features a scope with 2× magnification optics mounted on a rail set into its carry-handle and feeds from magazines of 36 rounds.[1] Some notable differences between the BR75 and its predecessor include an accessory rail mount on the left side of the handguard, and a new muzzle brake, though some variants feature a 2P flash hider which further increase similarities to the BR55. It is a highly versatile weapon, capable of engaging targets at a variety of ranges,[4] and is particularly suitable for mid-range and long-range engagements.[5][7]

The weapon's side contains a barcode which translates to details of the weapon's manufacturer, the Misriah Armory facility at Eos Chasma, Mars.[6] However, models that are equipped with the 2P flash hider were standard for units manufactured on Reach.[8] Korolev Heavy Industries also manufactured some attachments for the weapon as well.[9] The sides of the upper receiver contain a proof mark indicating the weapon's year of manufacture and a certification that the weapon is safe to fire with nitrocellulose-based gunpowder. In the case of the BR75s supplied to UNSC Infinity forces in 2560, the weapons have the proof code FI, which translates to a manufacture year of 2558.[6]

Usage[edit]

The BR75 was in service by 2552. The rifle was used by First Lieutenant Maks Chapov during Blue Team's mission to Reach in 2559,[5] and continued to see use in 2560 during the Battle for Zeta Halo.[3]

Variants[edit]

  • BR75 DEVLOOP: A variant with custom built loadouts based on stock Misriah frames, designed originally to outfit premium security detail in sprawling industrial sectors.[11] It features a different muzzle brake, front handguard, carry handle, and chin guard.
