Looking for the ultimate turkey extra full choke ( my 612 came with FC) and was looking for either a CZ factory XFC or alternative supplier. Any suggestions? I looked at Briley web site but seemed like a confusing site to just pick the "US" guess and plunk down 90 bucks for a vented example, waitv6 to 12 weeks to find out it wasn't compatible with my 612 CZ pump
