Banshee sells a bunch of these on a daily rotating basis. So, only three main sources for this, outside of dismantling weapons you have that have these mods already.

Dragonfly Spec (Random Ada Mod Purchase) – Dragonfly explosion bigger with more damage. Sprint Grip (Random Ada Mod Purchase) – Faster handling after sprinting. Rampage Spec (Random Ada Mod Purchase) – Rampage lasts longer. Boss Spec (Sold by Banshee, Found in World Drops) – More damage against bosses (yellow bars).
