I have a SAKO A7, it comes with cheap injection moulded stock and floating recoil lug. What torque setting on my fat wrench do I need ? I emailed Sako 3 times, never received an answer. Then, do I alternate front and rear action screw when tightning, or do I do the front first till tight and then the rear??? Do I use the same torque setting for both action screws?
