The American model is true to the lines of the classic American sporter style rifle. Made without open sights, the top of the receiver is machined with a 3/8” wide dovetail groove for mounting standard rimfire dovetail mounts. The CZ 455 American comes with a 5 round polymer magazine with an option to buy a 10 round magazine. The safety is located above the rear of the bolt and provides a positive firing pin block.
"In the new generation of the CZ rimfire rifles we have managed to combine experience accumulated over the years of development and production of this type of firearms with traditionally high quality, long service life, accuracy and modern trends. This new model of the CZ 455 rimfire rifle is based on classical design, but incorporating a lot of improvements affecting most of the main parts of this rifle. First of all we have answered wishes by many of our customers for having an action enabling interchangeability of barrels. Adopting a new knowledge when making the barrel’s muzzle, which we have acquired in the course of development and manufacture of firearms designed for hunting at long distances, allowed shortening of barrel while retaining traditionally high accuracy. Also the stock witnessed placing of small changes in order to achieve an even greater komfort during shooting. This was attained by optimizing the grip ergonomics, among others, in the pistol grip area. A new method of connecting barrelled-action with the stock is now dominated by only two screws with improved interface securing simpler tightening and superior appearance."
