Kriss Vector Gen 2 Problems

In this article, we’ll look at common Kriss Vector Gen 2 problems and their solutions so you can keep your gun running safely and reliably. We’ll provide the information you need to regain your gun in peak condition.

Common Kriss Vector Gen 2 Problems And Their Solutions

1. Jamming Issue

Sometimes, a Kriss Vector Gen 2 rifle may jam due to a wide variety of reasons. This issue can be caused by something as simple as dirty ammunition or an improperly seated magazine.

Some common causes of this issue and how to address them are listed below:

  • Dirty Ammunition: All ammunition used in this firearm must be clean and lubricated. Dirty ammunition can easily cause the firearm to jam, so check your ammo regularly and keep it in good condition.
  • Improperly Seated Magazine: All magazines must be properly seated in the magazine well. If the magazine is not correctly inserted into the gun, it could lead to a jamming issue.
  • Poor Recoil Spring Installation: If the recoil spring is not properly installed, it could cause excessive force on the bolt, causing a jam. It is important to check that the recoil spring is correctly seated and tensioned.

2. Failure To Feed

Failure to feed is a common issue encountered when using this firearm. When this occurs, the gun fails to chamber a round or feed a new round into the barrel after firing one shot.

Several factors, including improper lubrication, faulty magazine springs, incorrect ammunition selection, or worn-out parts can cause this. To correct this issue, it is important first to identify the source of the problem.

One potential cause of failure to feed is improper lubrication. The Kriss Vector Gen 2 must be properly lubricated to function correctly.

If too much or too little oil is present, this can cause a malfunction in the firearm’s operation. Care should also be taken to ensure that the magazine is correctly lubricated.

Another potential cause of failure to feed is faulty magazine springs. If the magazine springs are too weak, this can cause issues with feeding rounds into the barrel.

Replacing worn-out or damaged magazine springs may help to correct this issue. Additionally, it is important to select ammunition specifically designed for use.

Finally, worn-out parts can also cause failure to feed issues. If any of the internal components are excessively worn, replacing them as soon as possible is important.

3. Bolt Lock Failure

Another common problem that owners experience is bolt lock failure. This issue can increase the risk of jams and misfires, making shooting your gun more dangerous than usual.

A weak hammer pin is one of the most common reasons a bolt lock fails. When this pin gets too worn out, it can mess up the trigger reset and cause the gun to cycle improperly.

To fix this, you’ll need to swap your weakening hammer pin for a stronger one.

Using dirty or corroded ammunition in your gun can create residue buildup along the bolt carrier and hammer pin, which stops it from resetting properly.

To fix this, clean your gun regularly and use high-quality ammo.

Another reason for bolt lock failure is an improperly adjusted gas system. This can mess up the cycling of your gun and cause the bolt carrier to not lock back into place. To fix it, adjust your gas system to tune correctly for the ammo you’re using.

Another possible reason may be experiencing bolt lock failure is an incorrectly adjusted recoil spring. If the recoil spring is too weak, it won’t be able to cycle the gun properly.

To fix this, replace your recoil spring with one tuned correctly for your ammo and keep it well-lubricated.

4. Trigger Pull Weight

Many Vector Gen 2 owners have reported an issue with the trigger pull weight, which it is higher than expected.

The most common cause of this problem is that the gun’s springs are either too weak or too strong, causing an imbalance in the gun’s mechanism. This could lead to a higher trigger pull weight than is ideal for shooting accuracy and comfort.

Fortunately, this issue can usually be solved by replacing the springs with the correct strength and tension.

It’s important to consult a professional gunsmith if you are unsure which type of spring to purchase for your rifle.

In addition, if you have made any modifications to the gun recently or if there is any foreign debris inside of it, these could also be contributing factors and should be checked before replacing the springs.

5. Failure to Eject

The rifle can suffer from a common issue known as “Failure to Eject.” This happens when the gun fails to cycle properly and eject spent shell casings.

Sometimes, it may also fail to feed new rounds into the chamber.

The first step is to make sure the gun is properly lubed. Ensure all moving parts are sufficiently lubricated and no dirt or debris has accumulated on any gun part. If you believe the issue may be related to a lack of lubrication, applying a quality firearm lubricant should help solve the problem.

Sometimes, the issue may be related to a weak or broken recoil spring. If you suspect this is the case, you should replace the recoil spring with a new one as soon as possible.

Finally, make sure that all components are correctly installed and functioning properly. Ensure that all pins, springs, and other parts are securely in place and functioning properly.

If none of these steps are successful, then it’s best to consult a qualified gunsmith for further assistance.

7. Misaligned Sights

Misaligned sights on the Vector Gen 2 are a common issue that can lead to accuracy problems. Fortunately, this is an easy problem to diagnose and fix!

The most likely cause of misaligned sights is when the sight base screws become loose or overtightened. Make sure you check these before attempting any other fixes.

Check for any screws that may have come loose, as this is the most common cause of misaligned sights.

If the sight base screws are tight, adjust the front sight post and windage screw. This can be done by simply turning the windage screw until it is aligned with your point of aim.

Finally, if the above two steps do not resolve the misalignment, you must use a sight alignment tool. Insert the metal rod of the tool into the back side of your front sight post and turn it until it is aligned with your point of aim.

8. Stiff Magazine Release

This issue arises when the magazine catch spring does not provide enough tension for easy removal. Fortunately, this problem can be quickly solved with a few simple steps.

First, remove the lower receiver from the upper receiver by pulling down on the takedown pin. This will separate the upper from the lower receiver, exposing the magazine release spring inside the lower receiver.

Once exposed, press down on the magazine catch spring and move it up and away from its original position. Use a small flat-head screwdriver to ensure the spring is firmly in place.

Finally, reassemble your Vector Gen 2 and test the magazine release. If the issue persists, you may need to add more tension to the spring or adjust its position.

9. Stove Piping Issues

One of the most common issues with the Kriss Gen 2 is “Stove Piping”, which occurs when a spent casing gets stuck in the ejection port and prevents further loading of cartridges.

Several factors, including improper gun maintenance, weak ammo, or incorrect bolt manipulation, can cause this.

It is important to properly clean and lubricate the gun between uses and make sure only high-quality ammunition is used.

Additionally, ensuring that the bolt is fully retracted and locked back after each shot can help prevent future Stove Piping issues.

Lastly, if you encounter Stove Piping issues, do not attempt to remove the spent casing with any tools; instead, seek professional help to ensure the gun is safely cleared.
