Works smoothly and normally. Removed the fire control unit, cleaned and lubricated. Removed the forend and barrel, cleaned the action tube (exterior), cleaned the piston and also replaced the O ring to insure the gun functions as good,The bore is smooth and very bright with no visible defects.I would have to say it's a 10 out of 10 as it looks as good as new. The stock is also in excellent condition with no scrapes,dents or scratches
