CZ-USA 457 AT-ONE Varmint | .22 LR | 16.5″ Threaded | 5rd | 02365

The CZ 457 AT-ONE Varmint is a rimfire bolt-action rifle configured as a full-size trainer and field rifle. It features a 16.5″ heavy, cold-hammer-forged barrel with factory threading to accept muzzle devices, a Boyd’s AT‑ONE laminate stock with an adjustable comb and length of pull, and a detachable 5-round magazine. The receiver is drilled and tapped and the rifle ships without iron sights, providing a platform intended for optics. A solid mid‑range optic that pairs well and stays under $1,000 is the Vortex Crossfire II 2-7×32, which balances low weight, clear glass, and value for precision rimfire work.
