I remove the bold trigger by taking the screw out of the barrel. Pay attention not to loose the screw that puts it all back together. I then put the entire trigger assembly in hot dish soapy water and brush it off real good, and swirling it around. After that I rinse it with real hot water and shake it out. I then take some aerosol spray gun solvent cleaner which not only cleans any parts but acts as a drying agent, and spray the trigger down, inside and out. WD-40 would act as a drying agent but I do not like using it on triggers. After spraying it down, I shake it out real good and wipe it off. You will notice it is dry now. I then put a drop of oil into the top of the trigger by the black trigger trip and into the back side of the trigger I put a drop onto the internal working of the trigger. I also wipe the outside out with a oil patch.

After you install the breech plug, then you put the trigger assembly back in placebefore you put the hammer, cocking lever, spring and finally the locking lug (in that order). The gun is now assembled....
