Burris FastFire IV Problems You Should Know {2024}

Published on:

I’m here to share my hands-on experience with the BURRIS FastFire IV red dot. As someone who’s spent a lot of time testing this gear in the field, I’ve run into a few snags. 

During my time with the FastFire IV, I stumbled upon some common Burris FastFire IV Problems that seemed to pop up more often than not. We’re talking about zeroing issues, a cracked reticle, and that pesky flickering red dot that can be a real headache. 

I will dive into these problems, break them down, and, most importantly, offer some practical solutions.

Zeroing IssueRecheck installation, reset to factory settings, test on a different firearm, or contact the manufacturer for support.
Reticle CrackedAssess the damage and return under warranty if it’s a significant crack.
Flickering Red DotReplace the battery and ensure tight electrical contacts; seek professional help if the issue persists.

Top 3 Burris FastFire IV Issues & Their Solutions

1. Zeroing Issue

My first day at the range with the BURRIS FastFire IV was a bit of a letdown. Here’s the deal: I tried to zero the red dot, aiming to adjust it up, down, left, and right. 

But no matter what I did, my shots consistently veered off to the same spot on the left. Initially, I thought maybe it was just me. 


When faced with a zeroing issue like this, the first step is to recheck the installation. Make sure that the red dot is mounted correctly and securely on your firearm. 

Next, you’ll want to reset the sight to its factory settings. This often involves adjusting the windage and elevation settings back to their original positions. 

If the problem persists, it’s time to test the sight on a different firearm to rule out any compatibility issues. In cases where these steps don’t solve the problem, it could indicate a defect with the sight itself.

In such a scenario, contacting the manufacturer for support or considering a replacement becomes the practical solution. Remember, a reliable zero is crucial for accurate shooting, so don’t hesitate to seek professional help if needed.

2. Reticle Cracked 

So, here’s a curveball I didn’t see coming with the BURRIS FastFire IV. Picture this: I was using a Beretta 92X, loaded with 9×21 135 grain ammo, and all seemed well until I noticed a crack in the sight glass. 

This was no superficial scratch; we’re talking about a full-on crack right across the reticle. It was one of those moments that make you do a double-take. You might be wondering, how did this happen? Well, it’s hard to pin down the exact cause. 

Could it be the recoil, a manufacturing flaw, or just bad luck? Whatever it was, a cracked reticle is no joke. It compromises the sight’s integrity and, more importantly, your shooting accuracy.


Faced with a cracked reticle, the solution was pretty straightforward. The first step is always to assess the damage. If it’s a minor scratch, sometimes you can live with it. 

But a crack like this? That’s a different story. The solution I went for was to return the sight under warranty. It’s a no-brainer, really.

When you encounter a problem like this, especially if it’s a manufacturing defect, make use of that warranty. I contacted the manufacturer, explained the situation, and sent the sight back. They were pretty helpful, which made the process smoother. 

3. Flickering Red Dot

Here’s a tricky issue I encountered with the BURRIS FastFire IV: a flickering red dot. It started happening out of the blue. Initially, it seemed fine, but then, with each recoil, the red dot began to flicker. 

This wasn’t just a minor annoyance; it was seriously affecting my aim and focus. A stable and reliable red dot is crucial for precision shooting, and this inconsistency was a big problem. 

At first, I thought it might be a temporary glitch, but the issue persisted, making it clear that there was something more going on. The flickering seemed to worsen with more intense recoil, which made me suspect it was related to the power supply or the electrical connections within the sight.


To tackle the flickering issue, I went for a two-pronged approach. First, I swapped out the battery. It’s a simple step, but often, power inconsistencies can be traced back to a dying or weak battery. 

After replacing the battery, there was an immediate improvement, but I wasn’t done yet. Next, I decided to firm up the electrical contacts. This means making sure that all the connections within the sight are tight and secure.

 You’d be surprised how often a loose connection can cause problems like this. After tightening the contacts, the flickering issue seemed to resolve, at least for a while. It’s important to remember that these are temporary fixes.
