I have been using my M1A1 today and it has locked up on me every time i was wondering why? I have not had this problem with any other gun and i even tried to reload the software on my controller.
Are you using the box magazine? There are many reasons for getting bloked. Firing into smoke and airstrike , Unloading a full mag when its laggy and so on. Using rapid fire while operating the tank turret. What are you doing when you get capped?
