I am planing to sell this barrel but I am not sure if its broken or not. Its really really hard to adjust in the wheel in the middle and its easier to pull and push to adjust. I read somewhere on sotw that you can lock the bottom ring but im not sure if this is the one that does it. It looks like the one in this link but it have gold paint. It works when i play on it and i can adjust it just not with the wheel. Am i doing something wrong or did i broke it by adjusting it by pulling and pushing instead of the wheel?
