Just wondering why I never really see anything about the 512? I see pile of discussions about the 455 ad 452 but nothing one the 512. I'm wanting to get a semi rim fire rifle and it's my top pic but I never see them anywhere and i never hear anyone talking about them. Is there something wrong with them? Is it cause it only has a 25 round magazine? I thought that with so many CZ fans on here I would have seen and heard more about them.
