Hi Everyone. I love my new CZ 527 in .223. I almost wet my pants when I saw how accurate it is. But the bolt is rough, and it's difficult to make a follow-up shot without the bolt sticking at least once. The guys at the range said it was one of the worst they'd seen. They told me to dump FP-10 on it and if that doesn't work take it to a gunsmith. What will a gunsmith do to fix the problem and how much should I expect it to cost me?
