Wasn't sure where to post this... but I finally was able to pick up my CZ today and the first thing I did was change the sights to Dawson set up... fiber optic front and blacked out rear. After installation, I took the gun to the range for the first time and ran about 200 factory Winchester rounds through it. While cleaning the gun tonight I found a crack on the barrel and looking through the barrel you can see the rifling inside is damaged. I ran 200 rounds of factory ammo with no jams. Could this have been a manufacture defect? How do I go about getting this fixed? I just picked up the gun today. Thanks in advanced. Will post pictures soon.
