Forum:+1-2 find rare weapons mod?

So my cousin and I are playing as sirens, we have mods with +2 find rare items. My dad has a hunter build and i noticed on the wiki that a hunter mod has a +1-2 find rare weapon effect. We have farmed crawmerax and the armory around 200+ times combined and I have yet to see a hunter mod with this effect, does anyone have one? I would like to know that they actually are real and not something I keep farming for if it's not real.
