One of the biggest innovative things touted about the new CZ600 was that it had user changeable barrels/bolt heads that made it more versatile. Well the recall says that if the barrels aren't installed correctly they can still fire and I assume blow up. So what are they doing? They are permanently mounting the barrels in the receivers and canceling that feature. They already scrubbed the "Feature" from their website. Too bad, I always liked the idea of user caliber changes.
