Here are the real deal with AICS stock, you do not need additional bedding, Even on the HS PSS stock, there is no need to bed the action, the only people said that you need bedding are Usually Gunsmith...
Disagree and I just own very accurately shooting rifles.
The heavy torque on the action screws is a band aid solution to a poorly executed design. Can it function?...YES. Is it ideal? NOPE
Since HS was mentioned, I can say I have worked on a couple of these stocks that BENT the action when the action screws were tightened.
In ACCURACY circles, an interference fit between the action and the stock is critical to stable, consistent and accurate fire. That fit must not cause any bending/torquing stress on the barreled action.
Simple test, put the action in the CNC'ed drop in inletting without action screws. Can the action be moved within the bedding? The worse I have seen was 1/4" fore and aft plus rolling about 15degs from vertical. The only contacts the action made with the stock were through the action screws. The recoil lug wasn't even touching.
Put on the action screws and with your hand on top of the action, tighten and loosen the screws. Can you feel the action move? The worse was a visible movement of the action up and down. It took over 1/8" of bedding BUILT UP to level the action in the chassis. Try bending your action 1/8" and see how well it likes it!
Ever get ring marks even with mondo dollar super precision rings and bases?
If you have used the rifle for a bit, take apart and look at the action screw holes and recoil lug area. Any dark spots? Any signs of "burning", dust or shiney wear? Look in the action screw holes. Can you see thread marks?
Any bluing missing from under the action around the front action screw hole?
When shooting, ever get a few touching then one or more just out? Happens randomly no matter what load or ammo you use? Groups are still sub MOA but you wonder what would happen if all the shots went into the bughole group.
Usually the solution told is to put on a match barrel and accurize/true up the action. I bet you still have those flyers after you are done spending all that extra money.
A properly bedded stock will allow you to take a rifle apart and reassemble with no loss of zero. An alum chassis even at high torque will not do that repeatedly. Try it....
Once you have reviewed the above, make a decision whether bedding is worthwhile or not.
I read everywhere about the benefits of blue printing and action, holding alignment to a few thou. Most of this doesn't apply in a working rifle by the way. But if you have gone to all this trouble and expense, why would you throw this precision machined action into a stock then bend it?
