Common Mossberg 464 SPX Problems And Their Solutions

1. Feeding Problem

The culprit behind this issue can be the way you’re loading your rounds into the magazine tube. It’s important to note that for smooth feeding, you need to push the round towards the back of the tube and then let it drop in place.

If you try to load it directly into the front of the tube, it might get stuck or cause other feeding problems.

Solving the Feeding Problem

Here are some simple steps that you can follow to ensure perfect feeding of rounds into your Mossberg 464 SPX:

  • Make sure the magazine tube is clean and free from any debris.
  • Use high-quality ammunition that is compatible with your rifle’s caliber.
  • When loading rounds, push them towards the back of the tube and let them drop in place.
  • Avoid overloading the magazine tube, as it can cause feeding problems.
  • If you’re using a new rifle, it might take a few rounds for the action to break in and for the feeding to become smoother.

2. Failure to Eject

If you’ve been noticing that your Mossberg 464 SPX is failing to eject spent casings or is jamming frequently, then you could be facing some issues with the ejection system. This can happen due to a variety of reasons such as a dirty chamber, worn out parts, or improper lubrication.


  • The first step in solving this problem is to thoroughly clean the chamber of your gun. Use a cleaning rod and a patch soaked in solvent to remove any buildup or debris.
  • Check the ejection port for any obstructions or damage. If you find anything, use compressed air or a small brush to clear it out.
  • Inspect the extractor claw for wear and tear. If it looks damaged, it may need to be replaced.
  • Ensure that the gun is properly lubricated. Apply a small amount of high-quality oil to the extractor claw and any other moving parts.
  • If the problem persists, you may need to replace worn out ejector springs or other internal parts. Consult your Mossberg owner’s manual for instructions on how to do this or take your gun to a qualified gunsmith.

3. Extraction Problem

One of the most common issues with the Mossberg 464 SPX is extraction problems. This is when the spent cartridge fails to fully eject from the chamber after firing, causing a jam. This can be frustrating and even dangerous if not addressed properly.

The first thing you should check is the extractor claw. This is the part of the rifle that pulls the spent cartridge out of the chamber. If it’s dirty or damaged, it can cause extraction problems.

To check the extractor claw, simply remove the bolt from your rifle and inspect the extractor claw for any build up of dirt or debris.

If you see any, clean it with a soft cloth and some gun cleaner. If it appears damaged, you may need to replace it.

Another reason for extraction problems could be the cartridges themselves. Make sure you are using high-quality, factory-made ammunition that is appropriate for your rifle. Cheap or hand-loaded ammo can cause malfunctions in any firearm.

4. Hammer Issue

One common problem that you may encounter with your Mossberg 464 SPX is the hammer issue. This can be identified when your firearm fails to cock, leaving you unable to fire a shot.

If you’re experiencing this problem, first check the hammer spring. It may have become weak or broken due to frequent use and needs to be replaced.

You can purchase a new hammer spring from a reputable gun store or have a professional gunsmith do it for you.

Another common cause of this issue is lack of lubrication. Make sure to regularly clean and lubricate your Mossberg 464 SPX to prevent any malfunctions with the hammer.

5. Light Strike Problem

You may have noticed that sometimes the light strike on your Mossberg 464 SPX is not as crisp as you would like it to be.

This can cause issues with misfires and could potentially ruin your shooting experience. Fortunately, this problem can be easily solved.

The first thing you should check is if there is any dirt or debris in the firing pin channel. If there is, you can simply clean it out with a dry cotton swab or compressed air.

In some cases, a buildup of gunk and grime can hinder the firing pin from striking properly.

Another common cause of this problem is an insufficient amount of lubricant in the firing pin channel.

Make sure to regularly apply a small amount of high-quality gun oil to keep your firing pin functioning smoothly. This will also help prevent any corrosion or rust buildup.

In some rare cases, the problem may be due to a damaged or worn-out firing pin. If you notice that your light strikes are becoming more frequent and cleaning and lubricating do not solve the issue, it may be time to replace the firing pin.

6. Chambering The Rifle

One of the most common issues reported by owners of this rifle is difficulties with chambering.

If you’re experiencing issues with chambering, don’t worry, you’re not alone. This can be caused by a variety of factors such as dirty ammunition, debris in the chamber, or even an incorrectly sized cartridge.

To start, make sure you are using clean and properly sized ammunition for your rifle. Next, check the chamber for any visible debris and use a cleaning rod to remove anything that may be causing obstruction.

If the chamber is clean and the ammunition is correct, it may be an issue with the feed ramp. To access the feed ramp, remove your rifle’s bolt carrier group and clean both the chamber and feed ramp thoroughly.

After cleaning, reassemble your rifle and test fire it to see if the issue has been resolved. If you continue to have issues with chambering, it may be best to bring your rifle to a professional gunsmith for further inspection and repairs.
