I have a brand new CZ 455FS in .22LR, and it's a sweet shooting rifle. I already have a tack driving .22LR bolt action scoped Marlin, so I opted to put a Williams Receiver sight on the CZ instead of a scope. It really makes it a sweet little rifle. The aperture sight is ideal on the full stock model, since it has the European style stock which is made for iron sights. I got a 455FS with extra fancy walnut and it's a beautiful rifle; a real shooter and a keeper. I also have the option of ordering a drop in replacement factory barrel in .22 Magnum or .17HMR for the CZ455. You ought to give the CZ rimfires a look. They are superbly made rifles. So are the center fires.
