The accu-stock rifle uses the new style bolt release, that is located in the trigger guard. the accu-stock guns do not have the flat side cut into the receiver for the bolt release. The inletting is different so it will limit your stock choices.

Yes the accu-weds can be removed, and I highly recommend it because the accu-wedge places stress on the action and causes flyer's. IMO you would be better off just get a non-accu stocked rifle.
