Type-31 Needle Rifle

The Type-31 Rifle, also known as the Needle Rifle, is a Covenant infantry weapon.

Design Details
The Type-31 Rifle fires unconventional long and sharp projectiles similar to the Needler. The projectiles detonate several seconds after coming to rest in soft tissue.

Not much is known about this weapon, other than it is a medium-range, headshot-capable, two-hand rifle that only takes three hits on an unshielded opponent to cause an explosion, killing a player or enemy, rather than the seven of its smaller, one-hand-wieldable cousin, the Needler. It is noted as "combining the mechanics of the needler with greater flexibility and accuracy". It seems very similar to a Covenant Carbine, and very well could the be its predecessor.
