fatjack,
If you do remove the buttstock from the frame as described above be gentle and pull straight back, the side tenons are fragile and don't take torque very well. Also, if you get past this point and want to remove the firing pin assembly from the bolt, be mindful of the small rebound spring underneath the firing pin. It will come out with the firing pin and it is small.
Mechanically, the action is pretty simple and mostly visible with the butt stock removed.
