Mk 41 Gyrojet Heavy Machine Gun Mod
MODA prototype heavy machine gun from before the war.
If you're the insubordinate type, you can open the console and type "help gyro 4 weap" to view the ID for the Mk 41 Gyrojet in the brackets, then type "player.additem X" where X is the ID of the weapon to instantly own it.
Firemode is also a separate toggle, and you can even choose whether you want to use your Rifleman or Heavy Weapon skills when wielding the gun.
