Type-50 Directed Energy Rifle/Heavy

The Type-50 Directed Energy Rifle/Heavy or T50 DER/H, otherwise known as the Concussion Rifle, is a Covenant infantry weapon.

Design details
The T50 DER/H fires explosive bolts of superheated plasma. When the plasma bolt hits a surface, it produces area-of-effect damage and a small "kick" to its users and objects. It also has a slight downward arc to its shots, much like the fuel rod cannon from Halo:CE and Halo 2. The weapon has only seen limited use, its most notable combat deployment being the Fall of Reach. Because of its relative rarity, the UNSC has theorized that its use is restricted either by branch or unit.

The weapon has been described as the Covenant counterpart to the M319 Individual Grenade Launcher. In general, the Concussion Rifle resembles the Brute Shot, but has a different mode of operation: instead of firing a straight, linear-path projectile like a Brute Shot, the Concussion Rifle fires a plasma projectile that arcs due to gravity. This projectile's arc is less pronounced than a Wraith's Plasma Mortar, and is similar to the gradual arc of descent from a Fuel Rod Cannon's projectile. The Concussion Rifle, much like the Fuel Rod Cannon, is not very effective long-range due to its arc of descent.
