Which one is better: Burris Fastfire 3 or Vortex Venom?

I wanted to find out.

So I bought both red dot sights and hand-tested everything: reticle, battery life, durability, field of view, and so much more.

By the end of this Burris Fastfire 3 vs. Vortex Venom review, you’ll know which red dot is perfect for you.

Let’s get started.

Burris Fastfire 3 Red Dot

The Burris FastFire III is solid.

It puts an unmistakable red dot at the point of impact within your field of view, giving you an immediate advantage in speed and accuracy.

The lightweight construction and durable design can be used as a primary sight or paired on top of an existing sight, like a Burris AR-536 prism sight

The automatic brightness sensor can be adjusted to match the environmental conditions, or the shooter can choose one of three manual brightness settings.

Next, we got two MOA optics: 3 and 8. You might be wondering:

What is the difference between 3 MOA and 8 MOA red dot?

Choose 3 Minute of Angle (MOA) dot for pinpoint accuracy (popular on rifles).

Or choose an 8 MOA dot for fast target acquisition (ideal for short range shooters).

Lastly, the Burris Fastfire III will work with most optics-ready handguns…

…and the shockproof design stands up to years of punishing recoil.

  • PINPOINT ACCURACY: The FastFire III puts an unmistakable red dot at the point of impact within your field of view, giving you an immediate advantage in speed and accuracy.
  • LIGHTWEIGHT OPTICS: With lightweight construction and durable design, the FastFire III can be used as a primary sight or paired on top of an existing sight.
  • VERSATILITY DEFINED: Rely on the automatic brightness sensor to adjust to match the environmental conditions or choose one of the three manual brightness settings.

Vortex Venom Red Dot

The Vortex Venom offers speed and versatility, just like the Vortex Razor AMG UH-1 holographic sight.

High quality, fully multi-coated lenses deliver a crystal-clear sight picture and optimal low light performance.

In fact, if the watchers on the wall had this scope, they would have seen the ice dragon coming.

The illuminated, glass-etched reticle features eleven illumination settings to accommodate changing light.

Speaking of illumination, the reticle is a 3 MOA dot that is clear as day. It’s clean, crisp and bright.

Dot Size

The 6 MOA dot on the Vortex Venom has a distinct advantage since it delivers a crisper target acquisition. The fast acquisition of a moving target makes the Venom a better choice over the Burris.


In the hands of a seasoned veteran shooter, every 0.1 ounces can impact a shot, as such, the lighter Vortex Venom (1.1-oz) has an advantage over the heavier Burris (1.5-oz). 

Field of View

Both the Burris Fastfire III and the Vortex Venom are nearly equal when it comes to this category, but the Vortex Venom has a slight advantage in offering a broader field of view.

Elevation and Windage

The Burris Fastfire III provides a total elevation range of 115 MOA and a total windage range of 86 MOA. Against this, the Vortex Venom comes in with a total elevation range of 130 MOA and a total windage range of 100 MOA, giving this scrappy challenger a clear advantage over the defending champion, Burris Fastfire III.


Both the challenger and the defending champion are evenly matched in this category, but a slight edge goes to the newcomer. The Vortex Venom offers a lifetime lens coating warranty, giving the Vortex Venom a slight advantage over the champ. 

Battery Life

On paper, the battery lives of both scopes looks identical, but looks can be deceiving. The newer Vortex Venom delivers a stronger punch when it comes to a longer battery life. 

Which is better Burris Fastfire 3 or Vortex Venom?

After doing the Burris Fastfire 3 vs. Vortex Venom Review, my final verdict is:

The Vortex Venom is better than the Burris Fastfire 3.

Here’s why. It’s got:

  • Lighter weight (1.1 oz.)
  • Longer battery life
  • Easier adjustability
  • More illumination options
  • Slightly wider field of view

So if you had to pick one red dot sight, I’d go with the Vortex Venom. Feel free to give it a try:

If you don’t like it for whatever reason, you could always return it back to Amazon within 30 days for a full refund.   

That said, I’d like to turn it over to you:

1 thought on “Burris Fastfire 3 vs. Vortex Venom Review [2020]”

  1. Thanks for an excellent review. I have an 3 MOA Fast Fire III on my 12 ga. O/U Citori, which is my go to turkey gun which I like very much.
    After reading your comparison, I plan on going with the 6 MOA Vortex Venom on my Xtreme Plus, for duck hunting this year.
    Hopefully, I can mount it on the spreed bead mount I have on the gun. If it doesn’t match this sight, I’ll use the same Meadow Creek rib mount I have on my Citori that I am very pleased with.
