Defective BarrelClean the barrel and make sure there is no dirt or debris.
Failure to EjectClean the chamber.

1. Struggle Cycling

Cycling is difficult with the CZ 1012. When you are trying to fire quickly, it could cause you some problems as well.

In recoil, the cycling rate of the bullets is typically significantly slower compared to other models when they are positioned in unorthodox locations.

The Fix:

To solve the problem, the cylinder and cycling rails should be cleaned frequently, especially after shooting dirty rounds or skeet/trap in the winter. It can get slow and sometimes it will not fully cycle into the battery.

2. Jamming

For the CZ 1012, the jamming issues are distinct. When using shells, the identical jamming problem occurred.

If you load a gun with a top chamber, it will fire and discharge the shell in the correct place. However, the following shell ejects from the second chamber, but the lever is stuck in the firing position.

In addition, the choke tubes on this CZ 1012 frequently become jammed in the barrel.

The Fix:

You need to take the rifle apart, clean it, and then oil it. Make sure the components of the shotgun are free from any kind of dirt or junk.

The chamber needs to be cleaned. After doing all that, try using the rifle. If the problem persists, visit a gunsmith or contact CZ for a solution.

3. Choke Tube Gets Stuck

The choke tube often becomes jammed on the CZ 1012. Some people’s choke tubes get so jammed that it takes them days of experimenting with different techniques to remove them.

The barrel and chokes expand at different rates, leaving a small space between them where gunk can get stuck. When too much gets jammed in, it makes it hard to get out.

Small bits of plastic have been stuck in the gaps between the tubes and the barrel. It is possible that the plastic is a shot cup or wad.

The Fix:

At first, ensure that the choke screws are greased. Choke tubes that have been dropped often become soiled, and in certain cases, the tubes themselves may be slightly out of round.

Then, ensure that the choke tubes are clean and in good condition. The barrel threads also need to be cleaned.

Also, when installing the choke tube, ensure it is tightened to the appropriate level.

4. Defective Barrel

Reports state that roughly 6 inches into the hole, there was gouge (poor machining) and a 3-inch segment of the bore seemed to be unlined. Clearly, the choke was not centered when it was machined for the chokes, as evidenced by the visible half-moon it produced.

The Fix:

The factory barrel provided by the CZ appears to be faulty. This could be due to debris or dirt lodged deep within the barrel.

To ensure that the barrel functions well, I suggest giving it a nice cleaning. Otherwise, you will need to send your firearm to CZ before you can get in touch with them.

5. Failure to Eject

The CZ 1012 has issues like failure to eject. A shell is fired, but it does not exit the weapon.

The problem is that sometimes the shell becomes jammed into the chamber and you can’t slide the bolt back to free it.

You will need to give the bolt a good whack backward to do this, and sometimes it takes more than just power to overcome the bolt’s inertia.

The gun chamber could be too dirty, the extractor claw could be broken, or some other issue could be to blame.

The Fix:

To solve the problem, you need to give the chamber a thorough cleaning and check the condition of every other part.
