Re: How to clean feed tube?
My experience with this rimfire design prompts me to advise against disturbing the feed tube. I had fits trying to get it to feed right after reassembly. There's something going on with the parts relationships that totally eluded me.
I think this is one of those situation where the expression "if it ain't broke, don't go around trying to fix it" goes double.
If it feeds, that's all you need.
