The stamped bottom metal of the
455 is gone, swapped for a classy two-piece interlocking system. 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.
