American Hunting Rifle aka "AHR" in Montana used to offer a "tuneup" for standard CZ's...trigger, stock fit everything.
They bought CZ 550 actions, built their own barrels and stocks and sold their version of the rifle in several variations from Full African DG to a lighter weight scaled down mountain guns...super looking and of course a little spendy, shot like lazer beams too. Be worth a trip down Google Lane to see if they are still around.
Used to see the guy at the Dallas Boat Show sometimes with a booth outside in the tent on the back side of Market Hal, but it's been a while since I went.
