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?
It is in The Directions for the Fat Wrench.
On wood stocks I torque to 60 inch pounds.
On synthetic stocks,including plastic stocks I torque to 55 inch pounds.
I have seen plastic stocks crack at 65 inch pounds after a season of shooting and hunting.The extreme cold weather here in Montana with hot and cold the same day I feel caused that.
I always torque in steps at half the torque rear and the front last and then torque to 55 inch pounds.
I came by that method using a dial indicator for stock stress and I always get less stock stress tightening the front last.
Hope this helps.
