Similar feedback to Akubone, check out Pursuit of Accuracy. He does a lot with CZs and uses a lot of Area 419 stuff on his guns. I think he did a video of mounting Arca rail on bottom of the Varmint. Not sure if he or another YTer did one for the AT-One (same rifle I have), which is a Boyd wood stock. I have the Arca style rail on all of my centerfire bolt actions, but am sticking with the Harris on the CZ for now. I believe my stock needs drilling, which I don't want to do, at least not right now.
I really like the flexibility of the Arca/RAT rail. Great stuff and lots of companies have adopted the dimensions for compatibility.
ETA: If/when you get the Arca rail, check with me. I might have a spare MPA RAT attachment.
