Do gooders all... Stock removal, cleaning, re-oiling are strate forward and a snap. But reassembly is a bitch. you will reduce the value if the gun by near $200 with the wrong screw drivers and not knowing how the tang reassembles... Wait now... No long tang? then it is pretty easy.
It is easy to remove the trigger housing after the stock is removed. Loosen the set screw above the pin the runs through the receiver. Drive out the pin with a brass punch. Use a wooden dowel against the trigger housing from inside the receiver and tap it down and out with a hammer. The trigger housing swings out. Make sure the trigger is cocked when the trigger housing is removed! If it isn't the mainspring will shoot out across the room. Don't pull the trigger with the housing removed! If you aren't mechanical and clever do not take out the trigger. If the mainspring comes out you will never get it back in by yourself.
