so I just unlocked fmj 2 and I got to attach it and it not showing it completely broken
fix you god dam game you had beta and tests and still can't get it right this is just a money scam
So if you want to use fmj 2 you have to equip both fmj 1 and fmj 2 to make it work. Can not use fmj 2 without fmj 1
All attachments that have a version 1 and a version 2, in order to have version 2, you MUST have version 1 attached first.
Same goes for GRIP 1 and GRIP 2.
