I started shooting ARA a couple of years ago with a CZ457 and a 8-34 Athlon scope. It is the best shooter in the price range required. Later I got into ABRA which separates classes by barrel diameter. The factory CZ barrel put me in the “big boys” class so I bought a Lilja replacement barrel that was a smaller diameter. Now if I shoot ABA, a barrel swap puts me back in compliance. The Lilja barrel is not kosher in ARA. Two set screws holds the barrel in place so the swap is easy, just needs rezeroing and some settling shots. I am very pleased with the CZ.
