The Z-750 Special Application Sniper Rifle, more commonly known as the Binary Rifle, is a long-range Forerunnerweapon appearing in Halo 4. It employs two core-mounted particle accelerators to propel a round with unparalleled stopping power that can bring down distant foes with one shot. When the round impacts an enemy, it causes them to disintegrate, similar to when a Promethean Knight is killed. It also has two zoom modes (5x and 10x) to fulfill its purpose as a long range precision rifle. The rifle emits a highly visible orange beam from its barrel when aiming, allowing opponents to trace the user's location.
Positioned near the scope of a Binary Rifle are two lights, one on each side. These indicate how many rounds are currently in the weapon.
The Binary Rifle is one of the few weapons in Halo 4 that causes targets to disintegrate from the killing shot's point of entry. The other weapons that yield this effect are the Scattershot and the Incineration Cannon.
