Neutron assault rifle

The Neutron Assault Rifle distorts the equilibrium of its target by blasting it with sonic booms. Once disoriented, the attacker can close in with a melee attack.

Prime continuity
Soundwave uses his Neutron Assault Rifle in combination with his Energon War Axe.

War for Cybertron
Neutron Assault Rifles were one of the most common weapons in use during the Great War. They were well-balanced and used a large clip of ammunition with a decent amount of punch behind its unassuming frame. They were toted by both Scientist and Soldier classes.

Fall of Cybertron
They were still in use during the latter days of the war in the lead-up to the launch of the Ark. A newer design was introduced around this time, sporting a whopping six barrels as opposed to the single barrel on the old model.

The rate of fire is estimated to be 600rpm
