The Battle Rifle-12, more commonly known as the BR12 Battle Rifle, was a firearm used by the United Nations Space Command and later the United Federation to Restore Humanity. Introduced in 2558 with the goal of phasing out the BR55 series, producibility was limited and the two similar weapons were used to together until the BR55's official retirement of its final variant, leaving the BR12 as the temporarily uncontested service battle rifle.
The BR12 featured two firing rates: semi-automatic and three-shot burst. Fully automatic capabilities were not included because of a soldier's tendency to use more ammunition than needed (However, it was included on the Special Forces model). The rifle also featured polymer parts, making it a very tough weapon. Weight was reduced by using polymer, bringing the weapon to only a mere seven pounds fully loaded. The BR12's M458 mod 0 Rifleman's Combat Optic featured the ability to tansition between a red dot sight and an up to 6X magnification combat sight. Other optics could be fitted via the rail system, and a 40mm grenade launcher was developed to improve a rifleman's combat capability. The rifle was known as one of the most accurate in the inventory.
