Can someone tell me what do i need to do to unlock it? Why is it greyed out, rest of the ammos added with the patch on other guns work properly

exactly the same thing - I was about to start my own thread but then I found yours
no idea why its blocked as also the requirement box in the upper right corner shows nothing
its just empty
did you manage to resolve this issue?

Same thing here. They probably forgor to unlock it, which is a shame, it would be neat.

so, this is a bug ??
