"I owned a very old tubular fed bolt action 410. It would no longer fire and would not eject the shell. When Charles gave me the 410 back, he had made parts that no longer existed. And my 10 year old nephew is still happy to this day with his functional 410. I doubt it will ever need repair again.
Charles has worked on numerous modern, brand new and very old diverse types of weapons for me personally. I have not found an edge or the end of his knowledge."
