Ruger PC Carbine Problems

Common Ruger PC Carbine Problems And Their Solutions

1. Failure to Eject

Several factors can contribute to this problem, including ammunition type, improper lubrication, or a dirty gun. However, one of the most common causes is weak ejection springs.

The ejection spring is responsible for ejecting the spent casing after firing.

If worn out or weak, it may not have enough force to eject the casing fully. This can be easily fixed by replacing the ejection spring with a stronger one.

Another possible cause is an improperly adjusted extractor. The extractor is responsible for gripping onto the rim of the cartridge and pulling it out of the chamber.

If it is not properly adjusted, it may not grip onto the casing firmly enough, leading to failure to eject. This can be resolved by adjusting the extractor to the correct tension.

Cleaning and properly lubricating the gun is also crucial in preventing failure to eject.

The buildup of dirt, debris, or excess oil can cause malfunctions in the ejection process. Regular maintenance and cleaning can help prevent this issue.

In some cases, failure to eject can also be caused by using low-quality or reloaded ammunition.

These may not have enough power to fully cycle the gun, resulting in the casing getting stuck in the chamber.

2. Failure to Feed

Failure to feed refers to a situation where the cartridge fails to enter the chamber or gets stuck while trying to do so.

This can happen due to various reasons such as improper maintenance, faulty ammunition or worn out parts.

To address this issue, it is important first to identify the root cause.

One common reason for failure to feed is a dirty firearm. It is crucial to regularly clean and lubricate your Ruger PC Carbine to ensure smooth operation.

Another possible cause could be the use of low-quality or poorly manufactured ammunition.

Sticking to reputable brands and checking for any defects in your ammunition before using it is recommended.

Additionally, worn out or damaged parts can lead to feeding failure. This can be easily fixed by replacing these parts with new ones from Ruger or a trusted gunsmith.

3. Trigger Stuck

One common cause of a stuck trigger in the Ruger PC Carbine is a faulty return spring.

This small but crucial component pushes the trigger back into its initial position after being pulled.

If worn out or damaged, it can fail to perform its function correctly, resulting in a stuck trigger.

Another potential culprit could be other faulty components within the trigger assembly.

These could include worn out or damaged parts that hinder the smooth functioning of the trigger mechanism.

Inspecting all components thoroughly and replacing any that show signs of wear or damage is crucial.

Sometimes, a stuck trigger may not be due to faulty components but rather an accumulation of dirt, debris, or excess lubricant in the trigger assembly.

Regular cleaning and maintenance can help prevent this issue, but thoroughly cleaning the trigger mechanism may resolve the problem if it does occur.

4. Jamming Issue

While jamming can be caused by various factors such as improper cleaning or maintenance, there have been reports of specific problems with the design of certain components in the Ruger PC Carbine that contribute to this issue.

One common cause of jamming is a misaligned or poorly fitted magazine. This can result in the bolt not properly chambering a round and causing a malfunction.

Another potential factor is low-quality ammunition, which can fail to cycle properly and lead to jamming.

In addition, some users have reported issues with the Ruger PC Carbine’s recoil spring and buffer system.

These components, responsible for absorbing recoil and ensuring proper action cycling, may not be well-suited for certain types of ammunition or shooting conditions.

5. Magazine Problems

One of the main causes behind these magazine problems is the design of the feed lips.

The Ruger PC Carbine uses a rotary magazine with two feed lips, which can be prone to deformation and misalignments.

This can cause rounds to jam or fail to feed into the chamber properly.

Moreover, some users have also reported issues with the follower being too short, causing it to tilt and get stuck in the magazine body.

This can result in the bolt not picking up a round during cycling, leading to feeding failure.

Although Ruger has tried to address these magazine problems by releasing updated versions with reinforced feed lips and followers, some users still experience issues even with the newer magazines.

This suggests that underlying design flaws may have yet to be fully resolved.

To avoid potential magazine problems with the Ruger PC Carbine, inspecting and testing magazines thoroughly before use is recommended.

This includes checking for deformities or misalignments in the feed lips and ensuring the follower functions smoothly.

6. Stovepiping

There are several potential causes of stove piping in a semi-automatic firearm like the Ruger PC Carbine.

One common cause is insufficient recoil energy, possibly due to using low-powered ammunition or not holding the firearm firmly enough.

Another possible cause is a dirty or poorly lubricated gun, which can affect the smoothness of operation and lead to malfunctions.

It’s important to note that stove piping can also be caused by issues with the magazine, such as a worn-out spring or improper loading.

So if you experience this problem with your Ruger PC Carbine, it’s worth checking your magazine and trying a different one to see if the issue persists.

7. Reliability Issues

Reliability refers to a firearm’s ability to function properly and consistently without experiencing malfunctions or stoppages. In simple terms, if a gun is reliable, it will fire every time the trigger is pulled without any hiccups.

Reliability issues often manifest as failure to feed, extract, or eject properly for the Ruger PC Carbine.

These malfunctions can occur for various reasons, such as improper maintenance, use of low-quality ammunition, or a faulty component.

Unfortunately, unreliable firearms can be dangerous as they may misfire or jam at critical moments. This is especially concerning for those using the PC Carbine for self-defense.
