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.
