I’ve made kills with this or an HDR with one more legendary attachment in 3 DMZ Hard matches now. 5 kills total. None have registered. Serpent Island Hard requires Legendary armor; but to prove it to myself I’ve looted it from 2 after I killed them.
Am I missing something?
The mission for the HDR laser (which you need for the barrel): (Use Legendary HDR equipped with any 5 epic attachments or higher to eliminate enemy players with legendary or higher-tier armor (0/8))
