The CZ 457 Target .22LR Single Shot Rimfire Rifle is a precision‑oriented bolt‑action competition rifle built around a fully adjustable aluminum competition chassis developed with Olympic shooter Matt Emmons. It features a single‑shot feed and a 26‑inch cold hammer‑forged Match grade barrel with a target crown that is designed to deliver very tight groupings at 50m, with a guaranteed 12mm, 10‑shot group performance at that distance. The rifle’s ergonomics are highly adjustable, including a three‑axis adjustable pistol grip, reversible and multi‑axis cheekpiece, side‑tiltable buttstock with multi‑axis buttpad, and a fully adjustable forehand riser, allowing users to fine‑tune fit for competition shooting. A highly tunable two‑stage Flyweight trigger lets shooters adjust pull weight, stage travel, overtravel, and blade position for a tailored feel. The extended, checkered bolt handle and single‑shot platform make loading smooth and natural, and the 11mm dovetail diffuser on the barrel allows mounting of front sights or balance weights. The rifle’s overall length and weight vary with configuration but reflect its target‑centric design for ISSF‑style competition shooting.
