To my knowledge it hasn't been 100% confirmed by the dev team, but the popular opinion in the community is that there is indeed a hidden third objective (from personal experience I tend to agree since I've unlocked certain gold parts seemingly at random).
60 x kills in x objective seems to be the rough estimate for most weapons. Just keep at it and you should eventually get what you're looking for 🙂
That’s what I am hoping, and thank you so much for answering. It also happened to me with m1A1 and that’s how I got it golden. It will keep on trying it till it is gone one way or another.
I have 550 headshots with the MAS 44 and I'm still stuck on objective 5. I even managed 19/20 headshots in one round. I've been using the gun since December and I'm sick of it now. I never liked the gun to begin with but I make it my goal to gold each gun so that I can be comfortable knowing I spent time on each... and besides it's just something to do.
I had a similar issue with the Selbstlader, but after 200 total headshots it did give me the achievement.
The MAS 44 challenge has been in my loadout for so damn long now it just makes me depressed to see it.
