I have a buddy that has a couple very nice CZ rifles that are really good shooters in their stock form. He wants to get rid of them for a very good price but I am curious about how they are to work on if I wanted to customize them with new barrels, bedding, bolt face work, accurizing type mods, etc. How are they when it comes to setting them up for true long range work? Any info would be appreciated. Scot E.
