AIM Sports does not specify what size crows foot is required to tighten the barrel nut, please contact them directly for further assistance.
The correct size is 1 5/16"
i did it with a 20" adjustable. If you have a large enough open end wrench you could do it with that. I couldnt get an aero precision barrel nut to work but this worked great.
