Thread: Cz rimfires

Hi guys,

My brother and I both have cz 452 .17hmr. The barrel profiles appear the same and length is same. Mine is labelled '452-2E ZKM American' and his is labelled '452-2E'. His has a darker walnut stock with checking on fore end and pistol grip and a shiny barrel. Mine has no checkering at all and a matte barrel.

Can anyone tell me the difference in models and what the ZKM stands for. We were both under the impression we just had the sporter model American cz.

Thanks
