I haven't played with the 457 series rifles yet, only the 452 and 455's. I put an At-One stock on a 527 Varmint in 204 Ruger that has a Weaver 6.5-20X scope on it. The scope's objective hit the barrel in Warne medium rings so Warne high rings are used. This raised the scope to high for my general use so I decided to give the At-One stock a try. It's worked out well so far. For the money it's a nice stock. If I regularly changed my stock settings it wouldn't be my first choice but for a set it and leave it set up it works pretty well. It looks like yours is going to be pretty slick.
