A3-21's Plasma Rifle

A3-21's Plasma Rifle is an upgraded version of the normal Plasma Rifle that does 5 more damage at max energy weapons and condition. It is possessed by Harkness, and can be received by the player character through two of the endings of The Replicated Man quest. It can be repaired with normal plasma rifles. It is very effective and many times a head shot especially on weaker enemies will result in a one shot kill.
