Common CZ  Scorpion EVO 3 Problems and Their Solutions

1. Feeding Issues

Feeding issues are the most common problems encountered with the CZ Scorpion Evo 3. The Evo 3 is a semi-automatic, magazine-fed, 9mm pistol caliber carbine.

The firearm is popular for use in competitive shooting and home defense. Despite its popularity, the Evo 3 has been known to have some issues regarding feeding.

When a magazine is not properly seated, or when the magazine is empty, the gun can have difficulty chambering rounds. This results in a failure to feed (FTF) issue.

Fortunately, some things can be done to help fix this issue.

The first step is to ensure the magazine is properly seated in the gun.

This can be done by pushing the magazine up into the gun until you hear the magazine click into place. It’s also important to ensure that the magazine is full. This can be done by checking the number of rounds visible in the magazine. The next step is to clean the gun.

This should be done at least once every 2 weeks or whenever you notice the gun is having problems. To do this, you’ll need a good quality gun cleaning kit.

This will help to remove any dirt or debris that may be causing the gun to malfunction. Once the gun is cleaned, it’s important to lubricate the gun. This should be done with good-quality gun oil.

Finally, the gun should be inspected for any damage or wear.

This should be done regularly and addressed immediately if any damage or wear is found.

2. Trigger Pull Problem

The trigger pull problem is characterized by a light trigger pull that can cause the gun to fire unexpectedly. This can be an extremely dangerous issue, leading to unintentional firearm discharge. Fortunately, this issue can be easily resolved with a few simple steps.

The first step is to inspect the trigger mechanism of your CZ Scorpion EVO 3 to ensure it is functioning properly.

If you find any obvious signs of damage or wear, take the gun to a qualified gunsmith for repair. The next step is to adjust the trigger pull of the gun.

Most CZ Scorpion EVO 3s come with adjustable trigger pulls, and you can adjust the pull weight to your preference.

To do this, use the adjustable trigger pull screws to increase or decrease the weight of the pull. If you are still experiencing problems with the trigger pull of your CZ Scorpion EVO 3, it may be time to replace the trigger assembly. This is a relatively simple job that can be completed with a few basic tools.

Once the new trigger assembly is installed, you should have a much smoother and more consistent trigger pull.

3. Magazine Release Problem

The magazine release problem occurs when the shooter presses the magazine release button, and the magazine fails to come out of the gun.

This can happen for various reasons, but the most common cause is an incorrectly installed magazine.

To resolve this issue, the shooter must ensure the magazine is properly installed by aligning its follower with the bolt and pushing it down until it snaps into place.

Another possible cause of this problem is a worn-out magazine release button.

This is a common problem with the Scorpion EVO 3, and can be easily fixed by replacing the magazine release button with a new one. If the magazine release button is worn out, it may not be able to correctly hold the magazine in place, leading to the issue of the magazine not coming out of the gun.

Finally, a worn-out magazine spring is another possible cause of the magazine release problem.

The magazine spring is responsible for keeping the magazine in the proper position in the gun; if worn out, it can cause the magazine to fail to come out.

The shooter should replace the magazine spring with a new one to fix this issue.

4. Failure to Go Into The Battery

You’re not alone if you’ve encountered an issue with your CZ Scorpion EVO 3 failing to go into the battery. Many users have experienced this issue, and it can be quite frustrating. Fortunately, you can take a few steps to fix this issue and get your CZ Scorpion EVO 3 back in working order.

The first step is to make sure the bolt is properly aligned. If the bolt isn’t properly aligned when it’s inserted into the battery, it won’t be able to lock into place. To check this, use a flashlight and look down the gun barrel. If the bolt isn’t aligned, you can use an Allen wrench to adjust the position of the bolt.

The second step is to make sure the charging handle is properly engaged. Pull back on the charging handle to do this, and make sure it moves freely. If it’s difficult to move or feels stuck, you can use a flat-head screwdriver to adjust the position of the charging handle.

The third step is to make sure that the battery is properly inserted. If the battery isn’t properly inserted, it won’t be able to lock into place. To check this, remove the magazine and the charging handle and ensure the battery is completely inserted.

The fourth step is to ensure the recoil spring is properly seated. If not, it can cause the bolt to jam and not go into the battery.

To check this, remove the charging handle and the recoil spring and ensure the spring is properly seated. If it’s not, you can use a pair of needle-nose pliers to adjust the position of the recoil spring.

Finally, if you’re still having issues with your CZ Scorpion EVO 3 failing to go into the battery, you may need to do a complete disassembly and inspection of the gun.

A qualified gunsmith or a knowledgeable person should do this. If you don’t feel comfortable doing this yourself, you can always take the gun to a gun shop for a thorough inspection.

By following these steps, you should be able to fix the issue with your CZ Scorpion EVO 3 failing to go into the battery. If you’re still having issues, it’s best to seek the help of a qualified gunsmith or knowledgeable person.

5. Failure to Fire

The failure to fire issue is caused by various factors, ranging from a faulty magazine to a worn-out bolt carrier. It’s important to note that the issue can be caused by a combination of factors and not necessarily one single issue. First and foremost, ensuring your magazine is in good condition is important.

If the magazine is worn out, the spring may be weak, or the magazine may be feeding incorrectly.

Replacing the magazine should solve the issue.

Second, ensuring the bolt carrier is in good condition is important. If the bolt carrier is worn out, it can cause the rifle to jam or not cycle properly. Replacing the bolt carrier with a new one will usually fix the issue.

Third, it’s important to ensure the rifle is properly lubricated. If the rifle isn’t properly lubricated, it can cause it to jam or fail to cycle. Regularly cleaning and lubricating the rifle should help to prevent this issue.

6. Bolt Catch

The bolt catch is an important part of the firearm. It prevents the bolt from flying open when the gun is fired. If the bolt catch is not working correctly, the gun may fail to fire or fire without cycling properly.

This is an issue that can be dangerous and should be corrected immediately. Fortunately, CZ has a few solutions for the bolt catch problem. The first is to replace the bolt catch itself.

The bolt catch can be removed by unscrewing the two pins holding it. The replacement part is available from CZ and other gun parts retailers. The other option is to replace the entire bolt catch assembly.

This includes the spring and the lever that actuates the bolt catch. This assembly is available from CZ as well. This can be a bit more expensive than just replacing the bolt catch itself, but it ensures that all parts are in good working order.

Finally, it is possible to adjust the bolt catch on the Scorpion EVO 3.

This is done by loosening the two screws holding the bolt catch.

Once the screws are loosened, the bolt catch can be moved in and out until it functions properly.

This is a relatively easy fix and should be done if tinkering with the gun is something you’re comfortable with.
