3. carefully inspect the action/barrel assembly and check that it is clean and free of any foreign matter.
4. gently place the action/barrel assembly into the stock. Be careful not to damage or chip the bedding material in the
recoil lug area.
5. use the 5/16 x 24 hex head screws supplied to fasten the action/barrel to the stock assembly.
noTe: The screws are marked on the end with a letter (“f” for front, “r” for rear).
6. With the action/barrel assembly in place, use a torque wrench to tighten the screws to 80-85 inch-pounds. always
tighten the front screw first (the screw closest to the muzzle).This is accomplished when the handle “clicks,” indicating
the torque setting has been reached.
7. insert the complete bolt assembly into the rear of the action. ensure that the bolt stop clicks into the guide track in the
bolt body.
8. once the bolt is past the bolt release, you will have to depress the magazine follower to allow the bolt to go into
battery.
