CZ 457 At-One Varmint SR 22 LR 16.5" 5+1 Bolt-Action Rifle

The CZ 457 At-One Varmint SR is a bolt-action .22 LR rimfire rifle built around a precision 16.5" heavy-profile barrel. Part of CZ's modular 457 platform, this Varmint variant targets hunters and shooters who want a threaded, suppressor-ready rimfire with a fully adjustable stock.

The action is mated to a stainless steel receiver finished in low-glare black nitride, paired with a matching black-nitrided heavy barrel that is threaded at the muzzle for suppressor or muzzle-device fitment. A 5-round detachable magazine feeds the bolt for a 5+1 capacity. Controls include an adjustable trigger and a two-position safety. No iron sights are installed, leaving the receiver free for the optic of your choice.

The fixed Boyd's AT-ONE wood stock is this rifle's signature feature. The comb provides up to 5/8" of rise adjustment, and the length of pull can be set anywhere from 12.5" to 14.25" at the push of a button, letting the rifle grow with the shooter or fit a range of users. Overall length measures 30" and the rifle weighs in at 7.23 lbs, balancing well for prone, benchrest, or offhand work. The barrel uses a 1:16" twist, well-suited to standard 22 LR ammunition.
