This is a "Stock" photo used by Buds Cody. The UPC code comes back as "Stainless". Even CZ states : both barrel and action are finished in a matte bead blast. Barrel length is 20.5, and the bolt and bolt handle are finished in a hardy black nitride. http://cz-usa.com/product/cz-455-american-stainless-synthetic/

yes it is stainless 'The 455 American Stainless is meant to be a hardy, long-lived rifle that can be passed down through the generations. With the same swappable barrel system as all of CZ's 455 rifles, both barrel and action are finished in a matte bead blast. Barrel length is 20.5, and the bolt and bolt handle are finished in a hardy black nitride. This model combined with an interchangeable barrel system of the CZ 455 will allow the user to easily change the stock configuration as well as the caliber of the rifle. The 455 retains the accuracy and quality of the adjustable trigger, hammer forged barrel and billet machined receiver from the CZ 452. It also features an integral 11mm dovetail for scope mounting and a 5-round magazine.
