The Nylon 66 is a very hard gun to strip down and clean. At least in my experience. I got one used and have never seen a manual, yes, I know they can be found on the interwebz, but when it got a lot of use there wasn't any such thing. I usually just clean the barrel with either patches or bore snake and spray the bejeebers out of the action with gun scrubber and let it run out. I usually just go out the the driveway and let the stuff drain right there. Then I give it a little lube and good enough for me.
