My medium Engi uses Gerund (Four-Vent, Grip, Green-eye, Extended Mag) + CARB-9 (Four-Vent, Sling, Adjusted Sights, Duct-Tape). I used to use a Rhett, but I’ve found I prefer the Gerund’s higher accuracy and larger mag. I also just switched over from a Galactic to the CARB. My Medic, also a medium, uses Euston (Down-Vent, Grip, Green-eye, Extended Mag) + Drognav (Up-Vent, COGA, Rapid-Fire). My light Op uses a Bulpdaun (Six-Vent, Grip, Green-eye. Extended Mag) + SEagle (Up-Vent, Holster, Green-eye, Rapid-Fire). My heavy Soldier uses a Maximus (Dual-Vent, Green-eye) + Gerund (Four-Vent, Grip, Green-eye, Extended Mag). I also liked, when my Medic was a light, that same Drognav build with a Hockler (Up-Vent, Holster, Green-Eye, Extended Mag).
As you can probably tell, my playing style is probably a little different from most. I almost always go with accuracy and stability over power (Hence the muzzle brakes on everything). I also ADS an awful lot. I’m not sure how I’d manage without the Green-eye.
