A hand carried particle beam acceleration weapon. Its range is basically only limited by its five or 10x zoom scope, and atmospheric conditions. The rifle carries a power cell good for up to 18 bursts and charges very rapidly for a weapon of this type.
NOTE: Again a Covenant weapon largely designed to be comparable to a human weapon, although the rate of fire and the ammo capacity is handled differently. Here, as with most weapons besides the Needler and the Carbine, you pick up a Covenant weapon, use it until it is drained, and then discard it, since you can't recharge it. Presumably the Covenant are not so restrained.
