UNLOCKING CZ3A1

This is absurd, I recently moved so I wasn’t able to grind out the last few challenges or week of the limited time mode and now because of it I can’t get the fun? I have bf pro I grinded the first week and was hoping to finish before I moved but wasn’t able to. Now there’s no challenges nothing to unlock the weapon unless I play redsec and get 10 kills with it? What an absolute joke. They used to have a challenge to unlock a weapon if you missed the limited time mode. Now you just can’t unlock it. Absolutely horrendous design flaw for people who are more casual or just missed an event for any reason. Now I cannot utilize a gun in game after having preordered for a 100 bucks and still having to pay for BF pro every season? Absolute money grubbing, I’ve been playing bf for ages and have been a fan of every one of them but the way the treat the players is getting absolutely horrendous, they only care about money. It was their best launch and they handled post launch horrendously. Its truly sad what has happened to this franchise
