BR85 battle rifle

The BR85 Service Rifle is a select-fire battle rifle used by the United Nations Space Command.

History
The BR85 entered service as early as 2525, manufacturing concerns and logistical issues involved with its ammunition meant the BR85 was not widely adopted until after the Human-Covenant War ended. Prior to March 2557 several BR85Ns were delivered to Argent Moon. By October 2558 the carried a large supply of BR85Ns. At the same time Liang-Dortmund Corporation security forces stationed on Meridian carried a large supply of BR85Ns. Numerous BR85Ns were transported unintentionally to Genesis when Cortana began to recall the Guardians there.

Design
The BR85 Service Rifle is a gas-operated, magazine-fed battle rifle. A select-fire weapon, the BR85 is capable of firing three-round bursts and fully automatic fire. The BR85 is effective against most Covenant battle armor and the energy shielding of Sangheili harnesses and the plating of Promethean Soldiers; it also proves effective against the shields and plating of GEN2 MJOLNIR armor during War Games exercises. The BR85 can be fitted with a variety of scopes and receives a 36-round detachable box magazine.

BR85N Service Rifle
A variant of the BR85 featuring a smart-link open-topped holographic Recon sight was extensively used by the UNSC in October 2558.
 * Morph BR85N: Battle Rifle with Morph sight. Work continues on analyzing "resonance" exhibited by the Morph sight with certain weapons
 * Classic BR85N: Battle Rifle with Classic sight. Tactical configuration fitted with rugged combat optics preferred by veteran Spartans.
 * Longshot BR85N: Battle Rifle with Longshot sight. Marksman configuration preferred by many Requiem veterans.
 * Sentinel BR85N: Battle Rifle with Sentinel sight. Delta-Six special forces configuration with variable-zoom 4×/6× optics; optimized for long-range, pinpoint lethality.
 * Hybrid BR85N: Battle Rifle with Hybrid sight. Sangheili Carbine holoscope technology merged with human industrial methods. This is a Joint Task Force Sierra configuration undergoing evaluation by the UNSC Ordnance Commission.
 * COG BR85N: Battle Rifle with COG sight. Army SPECWARCOM configuration currently undergoing final evaluation.

BR85N attachments

Changes from BR85HB in Halo 4

 * Accuracy increased.
 * Shorter time between bursts and faster cyclic fire rate.

Trivia
Ironically, as with the M392 and M395 DMRs erroneously ejecting the signature shell casings of the Battle Rifle, the BR85N in Halo 5: Guardians now erroneously ejects what appear to be the M118 7.62×51mm shell casings of the DMR.
