The lock-on and anti-armor ammo for the LA's Rocket Rifle can be equipped but don't change anything. I believe this has been like this since launch of the NSOs and I have even told the support about this because I bought them with DBC. They said:
" This is actually an issue with certain loadouts/assets failing which has been escalated to the development team, and has become a very high priority to be fixed as soon as possible so that players can get the most out of their NSO character's loadouts. In this case, both types of rockets will be usable after the bug is fixed, or any DBC or certs spent will be reimbursed. "
That was 2 months ago...
