Mossberg 464 SPX Problems With Their Quick Solutions:

1. Feeding Problem:

Experiencing a feeding problem with your Mossberg 464 SPX can be a real bummer, especially when you’re at the range.

Every feeding failure messes up your target practice. But don’t worry; I’ve been there, too, and I’m here to help you troubleshoot and fix this issue.

One common issue arises when the magazine tube is loaded with shells, and the feeding system malfunctions, preventing smooth firing.

This can be caused by a misaligned magazine or using the wrong type of ammunition, both of which can disrupt the feeding process.

This frustrating problem often involves the spring tension or the liftgate, which are critical in ensuring each shell is correctly chambered.

Additionally, over-lubing can exacerbate the issue, making it essential to strike a balance when maintaining the gun.


When dealing with feeding problems in the Mossberg 464 SPX, focusing on the rifle’s action is crucial.

Start by thoroughly soaking the gun parts to remove debris. Then, using compressed air, blow out any excess lubricant, ensuring that the lubrication levels are adequate but not excessive.

Allow the components to dry completely before reassembling. During a tune-up, always run the rifle on the dry side of the regular operation to prevent frustration from recurring issues.

By maintaining proper lubrication and cleanliness, you can ensure smoother performance and a reliable shooting experience.

2. Failure To Eject:

Experiencing Failure To Eject can turn a day at the range into a frustrating ordeal. While testing the Mossberg 464 SPX, this issue reared its head more than once.

Picture lining up the perfect shot, squeezing the trigger, and then… nothing. It clings to the chamber instead of smoothly ejecting the spent shell casing.

This disrupts your shooting experience and can lead to misfiring and other safety issues. What’s worse, this isn’t a one-off occurrence; it’s a persistent problem that plagues many owners.

After delving into the mechanics, the culprit often points to a worn-out ejector spring. Under constant strain, this small but vital component can lose its resilience over time, leading to inconsistent ejection.

It’s a reminder that even in a reliable firearm like the 464 SPX, regular maintenance is critical to preventing issues in the field.


If you encounter Mossberg 464 SPX problems like failure to eject, do not fret. A simple solution lies within the ejector spring.

Over time, this component might wear out, causing ejection issues. I’ve encountered this, but a cautious approach and the right parts can swiftly resolve the dilemma.

Ensure you get the specific model of ejector spring for your firearm. A quick replacement of this small component can make a massive difference in the functionality of your Mossberg 464 SPX.

Once you’ve examined and identified the issue, swapping out the worn-out spring for a new one promises smooth, reliable shooting and eliminates the issue of misfiring shells.

3. Extraction Problems

During a recent field test, I encountered a vexing extraction problem with the Mossberg 464 SPX lever-action rifle.

After several rounds, the cartridge case stubbornly clung to the chamber like a determined hitchhiker, disrupting an otherwise smooth shooting experience.

Upon inspection, it became apparent that the culprit lay in a malfunctioning extractor claw, which failed to grip the spent casing securely.

This issue manifested inconsistently, sometimes occurring multiple times in a single session, leading to growing concern over the rifle’s reliability.

While initially dismissing it as a mere fluke, the persistence of the failure demanded a more head-on approach to resolution.


If you’re encountering extraction issues with your Mossberg 464 SPX, consider a simple solution.

Consider replacing the extractor claw, a delicate part prone to wear and tear.This new part can make a difference, swiftly resolving your problems.

With a quick consult of your manual, identifying the probable cause becomes a breeze. Invest the time to ensure replacement is done correctly, or consult a professional for peace of mind.

Once the part is replaced, you’ll return to business with spent shells smoothly removed and your rifle functioning like a champ.

Believe it or not, this simple fix can end your time with extraction issues, ensuring a hassle-free shooting experience.

My Final Conclusion:

The Mossberg 464 SPX is clearly with its challenges.

Some users have reported feeding and failure to eject issues, often stemming from extraction problems related to the ejector spring and extractor claw.

However, beneath these hiccups lies a solid design and performance rifle. While it may face machinery issues, they’re manageable with the right know-how.

Despite the challenges encountered, solutions reveal themselves through hands-on operation and ample time in the field, making the Mossberg 464 SPX a reliable choice.

My Friends Feedback

When my shooting buddies and I gathered at our local gun store (LGS), the topic of Mossberg 464 SPX problems always seemed to surface.

Despite its sleek design and promising features, several reports indicated issues with its lever action.

Compared to its counterparts, such as the Marlin rifles, Winchester, or Ruger, the Mossberg model had its share of complaints.

My friend, an avid gun enthusiast, shared his trouble with the lever guns, echoing sentiments I’ve seen on dedicated forums and YouTube videos. It’s not just about the trigger or safety issues; it’s about the function of the rifle as a whole.

I understand the frustrations many of you have expressed about Mossberg’s decision to introduce high-tech elements into a classic lever action design.

However, it’s crucial to address concerns regarding the Mossberg 464 30-30 Problems in order to provide clarity and potential solutions.

By acknowledging these issues, we can work towards improving the overall experience for users of this particular firearm model.

While these changes may have caused some issues, we can still enjoy the reliability and performance of the Mossberg 464 SPX with the proper knowledge and solutions.

Some even resorted to trigger kits and aftermarket parts to address the concerns about the sears and springs, but the underlying problems persisted.

While angle eject and lawyer safety features were meant to enhance user experience, they often contributed to the issue rather than resolved.

My friends often discussed barrels and scopes, pondering whether the December 2016 model had inherent flaws or was just a matter of individual customer experiences.

Despite the lever safety mechanisms in place, the consensus among us was clear: the Mossberg 464 SPX problem remained a point of contention in our shooting circle.
