Picked up a new 2013 VZ2008 and I found that I had a sticky bolt and no tab on the carrier.
After it shooting flawlessly, I was still worried about the potential for the trigger reset issue. I shot slow and fast and still it was flawless. So I took it apart and noticed that the bolt sticks if you pull it back ride it back slowly.
Once apart, I noticed that the bolt carrier was hanging on the disconnector when slowly released. For a minute I thought of smoothing out the sharp angles on it, then I talked myself out of dremel gunsmithing...thank god:)
I read about the disconnector and the tab fix in many threads, so i decided to look at original vz58 disconnector.
I found this
I compared that to my century and I found this
They are different, the century disconnectors angled edges vs the round top vz58 diisconnector replace the need for a tab on the carrier...it actually looks alot like my M&P 40 firing pin block safety...
