Top 4 Mossberg 930 SPX Problems & Solutions
1. Cycling Issue
Okay, first up, let’s tackle the cycling issue. When you’re out there, the last thing you want is for your shotgun to jam, right? But hey, it happened to me more than once with the Mossberg 930 SPX.
One minute, you’re aiming; the next, you’re left with a gun that refuses to cycle to the next round. It can throw you off completely.
The issue seemed more apparent when using certain types of ammo. The shell wouldn’t completely eject, causing the cycle to hang halfway through. Talk about frustrating!
Solution
So, what did I do to fix it? Well, first things first, make sure your shotgun is thoroughly clean. Trust me, you’d be surprised how much a little grit can mess things up. I took the time to break down the gun, give it a good cleaning, and lube the action.
Then, I switched to a different brand of ammo, one that was recommended for this particular shotgun. Boom, the problem was gone! Remember, folks, the quality of your ammo can play a big part here.
Don’t go cheap if you can avoid it; invest in some quality rounds for reliable cycling.
2. Feeding Problem
Next on the list is the feeding problem. I can’t tell you how annoyed I was when this happened. You’re out there, lining up your shot, and then—nothing.
The shotgun just won’t feed the next shell properly. It got stuck halfway, leaving me puzzled and frustrated. I tried shaking it a bit and gave it a couple of firm taps, but no luck.
Now, this is concerning because, in a time-sensitive situation, a feeding problem can cost you more than just your patience; it can be downright dangerous.
Solution
Alright, so how did I go about fixing this issue? First, I took a close look at the magazine tube and the spring inside it. I noticed some irregularities and wear and tear on the spring.
So, my first move was to replace the magazine spring with a new one. I also double-checked the follower to ensure it was sliding smoothly. And you know what? It worked like a charm.
To add an extra layer of reliability, I switched to using a higher-quality shell, which seemed to make a significant difference.
So my advice here: invest in a new magazine spring if yours is acting up, and don’t skimp on the quality of your ammo.
3. Failure To Extract
Moving along, let’s talk about the failure to extract the issue. Now, this is a headache you don’t want to deal with, trust me. I was at the range, pulled the trigger, and then got hit with a malfunction.
The fired shell casing didn’t eject as it should; instead, it stayed stuck inside the chamber. Yeah, it’s not what you want when you’re aiming for a smooth operation.
At first, I thought it was a one-time thing, but then it happened again. And again. That’s when I knew that I had a real problem on my hands.
Solution
So, what’s the fix? Well, I got down to the basics. Took the gun apart and carefully inspected the extractor and the ejector.
I discovered that the extractor had some wear that was affecting its grip on the shell casing. After replacing the worn-out extractor with a new one, things started looking up.
I also gave the chamber a good scrubbing to remove any built-up residue. Just to be thorough, I tested it multiple times with different types of ammunition.
The result? No more extraction issues! In short, if you’re facing this problem, check your extractor and clean your chamber.
4. Bolt Problem
Last but definitely not least, let’s dig into the bolt problem. You see, I was out there, gun at the ready when something just felt off. After firing, the bolt didn’t return to its original position, causing a complete stoppage.
If you’ve been around firearms, you know this is more than just a small snag. A malfunctioning bolt can lead to a whole host of other issues and could be potentially unsafe.
So there I was, safety on, scratching my head, and wondering how to get back on track.
Solution
Here’s what I did. First, unload the firearm and make sure it’s safe. Then, disassemble the shotgun to get a good look at the bolt assembly. I noticed that the bolt was sticking due to what appeared to be some gunk and friction.
So I meticulously cleaned the entire bolt assembly, even removing some small metal burrs that seemed to be causing friction. After that, I applied a high-quality gun lubricant to all the moving parts.
And guess what? Problem solved! No more bolt issues. To put it plainly, if your bolt’s acting up, a thorough cleaning and proper lubrication are your best friends.
