Using the popular Boyd’s AT-ONE® stock as its basis, this 457 Varmint variant makes an ideal trainer for the whole family. With the push of a button, length of pull can be adjusted from 12.5”to 14.25”. Comb height is similarly adjustable, with 5/8” of rise available.
In addition to the receiver-mounted, push-to-fire safety, CZ chopped almost an inch of length from the action and slab-sided it to reduce its footprint and weight.
The stamped bottom metal of the 455 is gone, swapped for a classy two-piece interlocking system. To make scope mounting easier, CZ 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 CZ has ever fielded.
