CZ-USA 457 At-One Varmint | .22 LR | Boyd’s Adjustable Stock | MFG# 02366

The CZ-USA 457 At-One Varmint is a rimfire bolt-action rifle built around a Boyd’s AT-ONE adjustable laminate stock and intended as a precision-capable trainer and small-game/varminter. It ships with a detachable 5-round magazine and a receiver that is drilled and tapped for optics. The muzzle is threaded with a 1/2×28 pattern, making common rimfire muzzle devices and suppressors straightforward to fit. A good optic pairing under $1,000 is the Vortex Crossfire II 3-9×40, which balances clarity, durability and cost for rimfire work.
