BR75 battle rifle

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

Design details
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. 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, and is particularly suitable for mid-range and long-range engagements.

The weapon's side contains a barcode which translates to details of the weapon's manufacturer, the Misriah Armory facility at Eos Chasma, Mars. However, models that are equipped with the 2P flash hider were standard for units manufactured on Reach. Korolev Heavy Industries also manufactured some attachments for the weapon as well. 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 forces in 2560, the weapons have the proof code FI, which translates to a manufacture year of 2558.

Usage
The rifle was used by First Lieutenant Maks Chapov during Blue Team's mission to Reach in 2559, and continued to see use in 2560 during the Battle for Zeta Halo.

Variants

 * BR75 Breacher: A modified variant of the BR75 with a reduced magazine size from 36 to 30, but improved stopping power and a higher rate of fire, for close-ranged encounters.
 * BR75 DEVLOOP: A custom built variant weapon designed for private security in industrial areas.
 * BR75 HAZCON: A modified version of the BR75 with part of the barrel wrapped in a fabric and the carry handle replaced. It was the signature weapon of the UNSC Army's 48th Chemical Brigade and the Office of Naval Intelligence's Green Light Teams.
 * BR75 [HCS] AKRIVEIA: Sport upgrade package for the BR75 designed for weight reduction and performance benchmarking.

BR75 attachments

In-game information
The BR75 holds 36 rounds in its magazine, and 216 rounds in reserve. Highly effective at longer ranges compared to the MA40 assault rifle, or Mk50 Sidekick, the weapon features burst-fire functionality, a slowed rate of fire, and slight recoil. Players are able to zoom in with a 3× magnification scope. The weapon notably has a four-burst kill potential.

Production notes
The BR75's firing sound was created from combining the sounds of the FN SCAR-H battle rifle and FN M240B medium machine gun.
