Hey all- I am considering barrels for my latest 10/22 build. I have a friend who has a never-been-fired Adams and Bennet blued 20 inch heavy barrel for sale a good price (told me 80 bucks). I have compared many barrels in the past, but have no experience with the Adams and Bennet. I heard they were made by Green mountain? Any truth to that? Just soliciting your thoughts and any experience with the Adams and Bennet barrel....... thanks in advance. Be safe.
