Z-750 binary rifle

The Z-750 Special Application Sniper Rifle, commonly known as the binary rifle, is a Forerunner energy channel weapon.

Overview
The binary rifle is a weapon used by Forerunner Promethean Knight units and certain types of Crawler units encountered on Requiem. The rifle uses two core-mounted particle accelerators to accelerate its projectiles to high speed, killing targets with one shot.

Design details
The weapon possesses an angular design and metallic casing. It appears to be held together, at least partly, by energy fields as indicated by its self-assembly process and floating sights. Orange highlights can be seen while the weapon is self-assembling and throughout the casing once assembly is complete; these highlights grow brighter when the weapon is fired. The sight through the scope is tinted orange and has two zoom levels, 5x and 10x. The rifle emits a highly visible orange beam when aiming, allowing opponents to trace the user's location.

Pros

 * Capable of destroying most vehicles (except Scorpions and Wraiths) with one or two direct shots.
 * Can instantly kill all forms of infantry (Spartans, Prometheans, Elites, etc.) with one shot (possibly two on Legendary).
 * High projectile speed; rarely misses within crosshairs.

Cons

 * The line of fire created by the scopes laser sight can be seen by everyone; giving away the location of the user.
 * Long reload time (roughly five seconds); leaving the user vulnerable.
 * Slow rate of fire (roughly four seconds between shots).
 * Low ammunition and clip capacity. Two shots per clip with three clips total (four with the Ammo Upgrade).
