Needler
From Halopedia, the Halo wiki
Summary
Very little is known about this Covenant weapon other than that it is a magazine fed weapon capable of automatic fire and target tracking.
Its projectiles penetrate soft targets no matter what the angle of impact. They ricochet off of hard surfaces at oblique angles, however, and are always deflected by energy fields, the only exceptions to this being the shields generated by the MJOLNIR battle suit and the Elite's combat armor. The composition and energy signature of its projectile is unknown. The manner in which the projectiles home in on their target is also unknown. It is likely that the Covenant themselves do not even know the specifics of the weapon's function, as they seem to have obtained it by modifying the Enforcer's Needler-like cannon.
Combat
One of the best ways to use this weapon is dual wielding against Brutes in Halo 2. About 6 seconds of auto-fire would kill a Brute.
The weapon can achieve a higher firing rate if the weapon is treated like a pistol, not a rapid-fire weapon.
