There is no doubt that both Burris and Vortex build some of the best optics on the market. In the compact red dot sight niche, there is an overwhelming number of options. A search on Amazon shows page after page of red dot sights from well-known manufacturers to names I can barely pronounce. Red Dot sights have become a staple item among shooters of all kinds.
Burris and Vortex Optics are two of the top contenders in this market. The Burris Fastfire 3 and the Vortex Optics Venom often compete head to head in the marketplace. I wondered how these two red dot sights stack up on paper when compared side by side. Let’s look at each of these red dot sights and then compare them to find out how they stack up and which of these sights comes out on top.
Burris Fastfire 3 Red Dot Sight Review
Burris Optics has been building fine optical sights since it was founded in 1971 by Don Burris. Burris has developed a reputation for quality, performance, and competitive pricing, from the first Fullfield riflescope series to the current array of night vision, thermal and mainstream optics. The Fastfire 3 red dot sight doesn’t miss the mark.
The Fastfire 3 is a small form-factor red dot sight designed for rifles, shotguns, or pistols. Small red dot sights have become the rage among pistol shooters. The low profile of these sights presents few problems for those of us who carry a pistol on a routine basis. The weight added to the pistol is negligible and the benefits almost always outweigh the negatives.
Let’s begin looking at the features offered with the Burris Fastfire 3 before we dive into the technical specifications.
- Automatic Brightness Sensor – The Burris Fastfire 3 includes an automatic light sensor. No more manual adjusting the intensity of the red dot when lighting conditions change. If you prefer to set the red dot intensity manually, the controls for this are easy to access and use.
- Easy Battery Replacement – Many red dot sights require you to dismount the optic to change the battery. That usually means a trip to the range to zero the sight again. Not so the Burris Fastfire 3. The battery compartment is located on the side of the sight for quick and easy battery changes without dismounting the sight.
- Maximum Battery Life – Burris advertises a battery life of up to 5 years. Such a long battery life is possible with the automatic time-out feature that turns off the sight when the firearm doesn’t move for a set period.
- Easy Mounting Systems – No matter what type of firearm the Burris Fastfire is mounting too, Burris has a mount solution. The Fastfire three comes with Picatinny or Weaver mounts for any application. Burris also offers a full line of accessory mounts for almost any firearm. The Burris mounting system is compatible with the Glock MOS system.
- Available Dot Sizes – You can choose from an 8 MOA dot size or a 3 MOA dot size. The larger red dot size is popular with pistol and shotgun applications. Many close-range shooters prefer the rapid target acquisition of the 8 MOA dot over the 3 MOA dot. Rifle shooters often opt for the 3 MOA dot size to ensure more precise shot location on targets at longer ranges.

Vortex Optics Venom Red Dot Sight Review
I won’t hesitate to say that I am a Vortex Optics fan. I have several Vortex Optics products in my gun safe. I have an AR pistol with a Vortex Venom red dot sight installed. For the money, I believe Vortex Optics to be some of the best buys on the market. Vortex Optics is a solid choice if you want above average quality, features, and performance at a reasonable price.
No matter the application, the Vortex Venom red dot sight can meet the challenges. Vortex has not shorted the shooter from the low profile design to the high quality glass, where it counts in creating the Vortex Venom red dot sight. Let’s begin this review by looking at the features that Vortex Optics offers with the Venom red dot sight.
- Fully Multi-Coasted Glass – the Vortex multi-coating provides the highest level of light transmission and reflective protection. Coatings on all air to glass surfaces provide maximum effectiveness and protection.
- Widefield lens – Featuring one of the widest lenses on the market, you also get an exceptional edge to edge resolution with no blurring or fading of the image. Better resolution from side to side allows faster and more precise aiming.
- Ten intensity settings – Ten levels of intensity settings for the red dot make finding the right level of brightness on the red dot for the prevailing conditions easy and quick
- Brightness Controls – The brightness controls on the Vortex Venom are side-mounted for easy access and adjustment, even when wearing gloves.
- Automatic red dot intensity system – Includes an automatic intensity level feature to adjust the red dot intensity to match the ambient lighting for best operations
- Unlimited eye relief – Unlimited eye relief allows quick target acquisition
- Parallax free operation – Every optic exhibits some parallax. In keeping with industry practice and standards, the extremely small amount of parallax is considered “parallax free,” and the impact on performance is negligible.
- 3 MOA red Dot – Small three MOS red dot makes target acquisition quick and precise for rapid shot placement with accuracy and confidence.
- Battery Life – At the lowest intensity setting on the red dot, the battery life extends to 30,000 hours. When left on the highest setting, you can expect the battery to last 150 hours.
- Top loading Battery – The Vortex Venom features one of the easiest batteries to install or replace. The battery is located on top of the optic and features a screw-down cap. There is no need to dismount the optic, no trays, or drawers to lose or break. Unscrew the cap, replace the battery, return the cap and screw tight and you are done.

I hate to hang my hat on price alone. When the comparisons on paper are so close, the choice then comes down to performance and the shooter’s preferences.
My Choice – The Vortex Optics Venom Red Dot Sight
My experience with Vortex Optics products over the years has been without a blemish. I have not shot many Burris scopes, so I can’t say my experiences with the two products are equal. I can say that I have never been disappointed with one of my Vortex Optics products.
The Vortex Venom optic that I have mounted on an AR pistol platform performs flawlessly. The gun typically rides in a custom rack behind the back seat of my pickup truck. The pistol endures all the bumps, bounces, and shocks of running off the road and down the highway. The Vortex Venom scope mounted on this AR pistol holds zero without fail.
