So I haven't maxxed anything out yet but I'm getting really close with a few weapons.. just wondering, when you upgrade and the equip limit increases on a weapon, do you have to buy another one of that weapon or do they automatically just give you another one to equip https://1921681254.mx/ https://100001.onl/?

For example, I have an arc torrent 10 and I need one more upgrade to increase its equip limit to 2 instead of 1 ... Would I have to buy another arc torrent 10 or to equip another one?
