Ruger Mark IV Problems You Should Know

Published on:

I’ve come across a Few Ruger Mark IV Problems that honestly, could be deal-breakers for some of you. 

We’re talking about jamming issues, trigger sensitivity, and some maintenance challenges. But don’t fret! I’ve got good news. I didn’t just find problems; I also found solutions. 

Problems I’ve Encountered & their Quick Solutions

StovepipingUse high-quality ammo, clean ejection port and extractor, lubricate bolt.
Feeding ProblemsUse full metal jacket rounds, clean feed ramp, lubricate moving parts.
Ejection IssueCheck and clean ejector, adjust tension on extractor claw.
Bolt IssueClean bolt and guide rails, lightly lubricate, align guide rails properly.

Top 4 Ruger Mark IV Problems & Solutions

1. Stovepiping Issue

So, stovepiping is one of the most frustrating issues I’ve encountered with the Ruger Mark IV. Yep, you heard it right. This is when a spent casing gets caught in the ejection port, sticking upright and blocking the action. 

It happened to me more than once during rapid-fire sessions, which was both annoying and disruptive. It’s a real rhythm-breaker, especially when you’re trying to get some consistent target practice. 

The problem is typically caused by weak ejection force, but it can also be a result of using ammo with inconsistent powder loads.


Alright, let’s talk solutions. I experimented with different types of ammunition and found that higher-quality, consistent ammo does help reduce the occurrence of stovepiping. 

Additionally, keeping the ejection port and extractor claw clean is crucial. A small brush or even a Q-tip works wonders for this. On top of that, regular lubrication of the bolt seemed to ease the ejection process, making it more reliable. 

So, a combo of good ammo, cleanliness, and lubrication solved this issue for me. Give it a try; you might find it as helpful as I did.

2. Feeding Problems

Feeding problems, gave me a real headache during my time with the Ruger Mark IV. It’s pretty much a textbook case of failure to feed, where the round doesn’t properly chamber. 

I’ve had instances where the round jams halfway or doesn’t make it up the feed ramp. And, let me tell you, when you’re out in the field trying to focus, this can be a huge distraction. 

After ruling out magazine issues, I realized that it’s often linked to the interaction between the ammo and the feed ramp, sometimes worsened by dirt or grime buildup.


Now for the part, you’ve been waiting for the fix. First up, I decided to pay attention to ammo selection. Full metal jacket rounds seemed to feed more reliably for me. 

Next, I focused on regular cleaning, particularly the feed ramp area. A dirty feed ramp can significantly contribute to feeding issues, so make sure it’s squeaky clean. Finally, I found that proper lubrication also made a world of difference. 

3. Ejection Issue

So, let’s chat about another issue I faced: the ejection issue. Sometimes, spent casings wouldn’t clear out of the ejection port properly. Instead of getting tossed out, they’d sort of just hang out in the action. 

It was beyond frustrating and impacted my overall shooting experience. You can’t really maintain focus when you’re dealing with stuff like this, right? In most cases, the ejector didn’t seem to provide enough force to fully push the casing out. 

It can be really frustrating when this happens, especially if you’re out in the field, trying to make every shot count.


Alright, onto the good stuff: how to fix it. One thing that really worked for me was to check the ejector for any signs of wear or damage. If it’s worn out, it won’t be able to provide the force needed to push the casing out. 

Another important thing is to maintain cleanliness. Dirt and grime on the ejector can affect its performance. So, a thorough cleaning session was in order. Last but not least, I found that adjusting the tension on the extractor claw can be a game-changer. 

A bit of fine-tuning and the ejection issues started to fade away. Always remember, if you take care of your firearm, it’ll take care of you.

4. Bolt Issue

Last but not least, let’s talk about the bolt issue. During my sessions with the Ruger Mark IV, I noticed that the bolt didn’t always slide back and forth as smoothly as it should. 

Sometimes, it would hang up, creating a delay or even preventing a new round from chambering. Trust me, a sticky bolt is no fun, especially when you’re going for accuracy and timing. 

It’s pretty clear that a malfunctioning bolt affects both the rate of fire and the reliability of the firearm. I’ve narrowed it down to issues with the bolt’s guide rails and, occasionally, the build-up of dirt or carbon in the bolt assembly.


So, how did I fix this? First, a meticulous cleaning of the bolt and guide rails was in order. Believe it or not, even a tiny bit of grime can impede the bolt’s movement. 

Once that was sorted, I applied a light coating of high-quality gun oil to the bolt and guide rails. The key word here is ‘light’; too much lubricant attracts more dirt. The last step was checking the alignment of the guide rails. 

If they’re off even slightly, it can cause friction and impede the bolt’s movement. After these adjustments, the bolt slid like a charm, making my shooting sessions far more enjoyable.

Also I’ve hands-on tested the Ruger Mark IV red dot sights to bring you an article grounded in actual experience.
