Have you removed the metal cap at the tip of the stock? The cap slides forward. Use a small screw driver or better yet a plastic pick of some sort to gently slide the cap forward. This should eliminate the final sticking point. If you still have trouble gently tap the underside of the receiver after all the bottom metal is off. The butt of a screw driver works well. Also I like to always take the bolt out before removing the stock on any rifle one less thing to bind up.
