CZ USA 457 At-One Varmint uses the popular Boyds AT-ONE stock as its basis, this makes an ideal trainer. With the push of a button, length of pull can be adjusted from 12.5" to 14.25". Comb height is adjustable, with 5/8" of rise available. The laminate stock provides a rigid platform to work and the threaded heavy barrel makes fitting a suppressor easy. 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. 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. The 457 now features a trigger adjustable for weight creep and over-travel. The stamped bottom metal of the 455 is gone swapped for a classy two-piece interlocking system. To make scope fitment easier CZ ditched the 90 degree bolt rotation in favor of 60 degree allowing for larger ocular bell diameters with lower ring heights. FEATURES: Adjustable trigger; 60 Degree bolt rotation; Two-Position Safety FINISH: BLACK
