CZ USA takes rimfire performance to the next level with the 457 Varmint AT-ONE. Equipped with the Boyd’s AT-ONE stock, this rifle can be finely tuned to fit the user’s preferred length of pull (between 12.5” and 14.25”) and cheek height (up to 5/8”) with the push of a button. This wide range of adjustability makes the 457 Varmint AT-ONE an ideal trainer for shooters of all ages. The Boyd’s AT-ONE stock also provides a solid foundation for the action and barrel, and a wide fore-end is perfect for riding sandbags. The barrel itself is cold hammer forged and is in the heavy profile, with 1/2x28” threads at the muzzle for use with a suppressor. The 457 Varmint AT-ONE’s bolt features a 60-degree throw, this was chosen to increase scope compatibility especially on scopes with a larger ocular bell and lower ring heights. Under the recommendation of US Hunter’s Education instructors and 4-H shooting coaches, the 457 Varmint AT-ONE is outfitted with an American-style push-to-fire safety – a configuration that American shooters are more accustom to. In addition, the 457 Varmint AT-ONE features a fully adjustable trigger, and an 11mm dovetail for installing optics.
