I have available a set of 6 Briley Titanium Choke tubes and 1 Diffuser which is not Titanium. Cost of these chokes are $750 including the wrench and are like new for $375. These are Crio not Crio Plus. These work If the threads start at the end of the barrel where the choke snugs up to the barrel. If your threads start a half inch into the barrel you need Crio Plus and these will not work.
