Re: Customizing CZ Rifles
I've a little experience. I've done two. I built a custom 260 on one (with my own hands), and trued, bedded, and tuned the trigger on another.
As a hunter / shooter I was happy with my CZ's. Lot of nice feaures, good accuracy, for a great price. As for working on them, they are something of a pain. Typical accurizing steps will be no big deal. Not slick like a Rem, but no big deal.
Only custom components I used were barrels. I'd make sure you can even find any aftermarket components you want. Acton threads are metric and very coarse. Make sure your smith will cut them. Straight Shot Gunsmithing will.
