The Proton Carbine MKII was the Demon's Talon primary weapon they used. It was a basic Proton Carbine but with heavy modifications, but still delivered the same killing power, but instead it had a better scope, and adjusted sights for Talon Soldiers. However it was still though a very weak weapon in comparison to other weapons of same type and class, but its high rate of fire would eat through armor at any rate.
