Upgrade system is super broken if you look at it. At the current state you can buy a gp gun and after 2-3 upgrades you can get nx-rare then sell it back for profit. Also if they do release the second they do I am buying M417 combat which goes to G36C then buying PSG - 1 Mod that goes to M107 Ghillie and then the m1911 knights which is usp tac se. It is to broken I think they won't put it in at it's current state.
