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. The stiff laminate stock provides a nice, rigid platform from which to work and the 16.5” threaded heavy barrel makes fitting a suppressor easy.
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.
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.
