Precision rimfire rifle competitions have been gaining steam in the last few years and CZ rifles have been go-to equipment for the sport. Expanding on our premium offerings, the Varmint Precision Chassis pairs our heavy-barreled 457 action with an aluminum chassis of our own design. Equipped with an adjustable Luth-AR stock, an AR-style grip, QD sling sockets and plenty of M-LOK slots, proper fit and customization are easy to accomplish. If we were to pick one thing that our previous rimfire platforms were lacking, it was an American-style push-to-fire safety — something Hunter’s Education instructors and 4-H shooting coaches have begged us to incorporate for years. Though that was the most obvious change, we also took the opportunity to tweak a load of small things at the same time. In addition to the receiver-mounted, push-to-fire safety, we chopped almost an inch of length from the action and slab-sided it to reduce its footprint and weight. To make scope fitment easier, we ditched the 90° bolt rotation in favor of 60°, allowing for larger ocular bell diameters with lower ring heights. To top it all off, the 457 now features a trigger adjustable for weight, creep and over-travel. With the exact same swappable barrel system as the 455 and the same reliable polymer magazine system, the 457 is without a doubt the best rimfire platform we’ve ever fielded.
