Turret Help

Recently, i have been pumping out dupes, and they are seemingly good. The only thing they need is a mouse aimable turret. I know that you can build a stationary one using a facer, but it has to be frozen. I also know that you can parent the facer, and it treats it likes its frozen, but then i can attach anything to it (atleast when i use the easy precision parenting). I really need help with this conflict. Ive also heard i might be able to use expression2, but i havent got that far in my wire learning yet. PLEASE HELP ME!
