When first produced the Alpine Mountain rifle did not have any extra machining done to the action. All of the weight savings were in the thinner barrel and stock. I am not positive, but I don't think they have changed that.
HOWA makes a very good rifle and I think their bottom metal is the best of its kind in a factory rifle. I have restocked them using 700 ADL guards because I prefer that set-up. They will benefit from bedding.
