These wrenches now come with a shiny stainless looking coating. You will need a 13/16 socket, a torque wrench, and a barrel vise in addition to the Impact Action Wrench. We recommend 75 to 85 ft. lbs. of torque when installing a barrel onto our actions. This wrench works on all Impact Precision actions.
Also, here are two good barrel vise options if needed:
Viper Barrel Vise
Short Action Customs Barrel Vises
