Whenever I had chrome on, the gun locked like no camo was on.Honestly I don't remember the last time I really cared for camos. I think WW2 was the game that made me prefer just a raw gun with how they had different variants of each gun. I might just go for some camos for the weapons I like.
Honestly, the Damascus camo seems like it will take an eternity if you're not exceptionally good and invest multiple hours every day. I dont have that time to invest in this game unfortunately. So I'll just wait for modded lobbies..
