Unarmed Combat and Thrown Weapons

Q: The sai has a range increment of 10 feet. Do you still gain the benefits of unarmed combat feats (increased damage dice, nerve strike, extra attacks if you have quick draw, etc.) when using the sai as a thrown weapon?

No, because it’s a thrown weapon in those circumstances.
