Ive gotten it to maximum level but I still cannot access the gunsmith of the weapon because I do not own the base variant, only a blueprint variant. Without the base variant, it seems you cannot access the gunsmith to change the attachments. And in the current state, the RAM7 mission can only be completed through Multiplayer activites and not Warzone, so f2p players cannot earn it. Even if we buy it like I did for $16, we cannot actually modify it at all. The square gunsmith icon is just not there to be clicked on. Hope you guys can fix this! Feels like I paid money for something I cannot really use how i want it to.
Ok. Its a bug we are in the process of fixing. Do me a favor and try this: - - - Deselect the blueprint from your loadouts by selecting another weapon. - Lock that in. - Now go to your loadout and see if you can select the base version of the Ram. If you dont have access to it the challenge should appear so you can do it. Let me know if this short term fix works. We are working the bug double fast but I dont have an eta on the update.
