Select fire, allows all automatic weapons (even from mods) to be toggled between full-auto, burst fire, or single shot. Really useful with how rare ammo is in Dust. https://www.nexusmods.com/newvegas/mods/49478
"last of us" flamer. Really great quality weapon mod, and fits thematically with Dust. Craftable too, so gives you something to work towards. https://www.nexusmods.com/newvegas/mods/63063
