This is something I found at some point written by Chris Bezzina of Savage Arms:

"Proper Adjustment of The Accustock
there is a specific technique for assembling the action into the AccuStock, and it needs to be strictly adhered to as follows:

1. Ensure that the recoil lug "wedge" screw is backed out to the point where the wedge has sufficient vertical movement to allow the recoil lug to seat against the bottom of the aluminum rail.
2. With the action inserted into the stock, justify the action toward the rear of the stock to allow the recoil lug on the action to be seated against the boss on the aluminum rail.
3. Tighten the forward most screw to 10 in.-lbs. to seat the action against the aluminum rail boss, then back out one-half turn.
4. Tighten the middle action screw to 10 in.-lbs.
5. Tighten the rear action screw to 10 in.-lbs.
6. Tighten the forward action screw to 10 in.-lbs.
Repeat steps four through six and increase torque value in increments up to a final torque value of 40 to 45 in.-lbs.
note: It is extremely important to tighten per the insructions above because when you are tightening the action down into the AccuStock you are spreading aluminum side rails and evenly moving the action down onto the base of the rail, ensuring positive engagement."
