I have upgraded,
3x Tacc ARS
2x VBI AR
1x Frontier Battle Rifle
1x Frontier Saw
1x VBI SMG
And 1x Zagger (but that doesnt really count since it was bound to get reload)
I have yet to get a damage roll on any of my 8 guns i have upgraded. Only fire rate and mag rolls.
Trion is there a nerf on getting damage rolls? Or do i just have bad luck?
