Once you‘ve leveled a gun at the end of the tree you can‘t change it anymore. Bug or feature?
Lets all really hope that its not a “feature” !
you can buy multiple of the same gun and go down a different rout so it is indeed a feature.
How you mean that?
if you are talking to me, select the “buy one more” button at the bottom of the screen of the gun you are wanting more of in the armory.
That’s a really stupid feature lol
I don’t think it’s stupid. This way you are forced to think about which role you want to play and upgrade your weapon accordingly. Your choices will give you an advantage on some maps and a disadvantage at other maps. If you can just change your upgrades whenever you want everyone will always play with the best possible upgrades for a certain map. You might as well remove upgrades all together in that case.
This ^
I still need to upgrade my weapons… 
Right, that’s exactly what we want. People buying multiple copies of the God weapon known as the STG44
