Per the new FAQ:
Target locks acquired using R4 Agromech’s ability may be used during that attack.
If a ship equipped with R4 Agromech is attacking with a secondary weapon that requires the ship to spend a focus token (such as a Blaster Turret or any weapon used with Deadeye), that ship cannot acquire a target lock on the defender because the enemy ship becomes the defender after the cost for the attack is paid. See "Timing Chart for Performing an Attack" on page 6.
You may spend 1 focus token to change all focus results to hit results only once during the "Modify Attack" dice step. See "Spending Tokens" on page 5
This seems to kill the uniqueness of Contracted Scouts as alpha strike platforms. They're still good, but now they're a lot closer to TIE Bombers, Y-Wings, etc...
