The newer production CZ Carbines now come with a modified bolt handle to allow easier scope clearance from the factory. That makes it a bit easier on the consumer. Both of mine were 2015 production if that helps anyone out there looking right now.
Mine didn't come with rings but some do. It's totally random! And the rings are expensive.
I sold off all my spare parts and eventually sold the rifle. I liked the weight of the gun and the size and feel of the stock but the function of it left me disappointed. I ended up getting a Ruger 77/357 which I like a lot better. Mind you its not perfect either but for this class of gun I like it a lot better. The only work I did to it was replace the rear sight and a trigger spring kit. It's probably my favorite rifle.
