Monolithic Supressor
18.7 Bowen Barrel
Axis Shift Vertical Foregrip
Greaves Cassin Stock
5.56 NATO FMJ
or if you value magazine size… replace the monolithic suppressor, this still maintains 1st stage damage range to be still at 50m
Mind you… 3 shield + base health = 300HP
with the 30 round mag version you only need to land 8 bullets to delete shields and their health to down a target because of the high damage per bullet, 39 damage up to 53 metres with this build.
