I have an At-One for my CZ and while I like the adjustable cheekpiece and length of pull, the trigger reach is too far for my tastes, even with the target grip panels. I really didn't think about it until I got my XLR chassis on my centerfire all dialed in. It fits me perfectly now, and I wish the At-One fit me as well. The inletting is very good and it looks nice, but I'm seriously thinking of retiring it and getting another chassis of some sort.
