The only "trick' to an Accustock is that the action bolts are in awkward locations. The front one is inside the hinged floorplate housing and the magazine follower gets in the way of the Allen wrench. A velcro strap can be used to compress the magazine spring to get it out of the way. The rear action bolt is under the bolt release in front of the trigger guard and you have to retract the release lever to get to it.

Remove both bolts and the action comes right out. There is a stickey here in this forum describing the torque sequence to reinstall the action in the stock but it's not that difficult.
