I see them for sale in Canada but not sure if they are ever in stock lately? Or if you can actually get them? Only ever see 20” listed, anyone know if 16.5” is also available? Do barrelled actions also have a “shot card” with them? I believe most CZ 457 complete guns come with a 5 shot group card of sorts, so wondering if the barrelled actions do? Maybe I am better off buying the 16.5” MTR stock version and drop the stock.
