CZ's 557 is a departure from the Mauser-style bolt found on CZ's 550 models. Instead, it has a short extractor and plunger-style ejector for smooth operation and enhanced ejection. The short extractor or "push feed" system also makes it easier to single load the rifle, which many shooters prefer for range work. The action is paired with CZ's legendary cold hammer-forged, factory-lapped barrel and dressed in an American-style walnut stock. The receiver is machined from steel billet and has CZ's integral 19mm dovetails for mounting a scope. Equipped with a 2-position safety, the bolt can be cycled while the rifle is on "Safe." To top it off, the 557 comes with a fully-adjustable trigger that allows the owner to tune weight, creep, and overtravel to their liking.
