Thanks i'm starting to think about a build and i think the BAT action will be my choice just wanted to hear some opinions.BAT is a nicer action IMO. I have about another month and my BAT Vampire will be done. I have both Defiance ultra light and BAT HR's. Defiance is a very nice action. But BAT is another level. Alex Wheeler has done some builds on the aluminum actions. He says they are smoother than an HR which is hard to imagine. The BAT aluminum actions are stronger than the ANTI-X as well.
