CZ USA 457 22 Long Rifle American Blued Bolt Action Rifle - 24.8in - The classic American-style rimfire rifle, the 457 has a 24.8in barrel with no sights and is meant to be topped with a scope. Its Turkish walnut stock has a high, flat comb and a classic checkering pattern. Like all of our 457's, it has an 11mm dovetail milled into the top of its receiver for attaching scope ring/mounts. In addition to the receiver-mounted, push-to-fire safety, we chopped almost an inch of length from the action and slab-sided it to reduce its footprint and weight.
