I am trying to complete the depleted exotic weapon core and I only need one more fusion rifle.. I never use the plan c so I broke that down with the character that holds the bounty but It didn't count towards the bounty. The task says "charge the core by dismantling 10 [u][b]rare or higher quality fusion rifles[/b][/u] I do believe exotic is a bit better than rare. I just want this bounty finished out.
