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.

Burris FastFire III Reflex Red Dot Sight for Rifles, Pistols and Shotguns

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.

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.

There isn’t a lot of difference physically or internally between these two sights.  For many shooters, the choice boils down to price and that is where the Burris Fastfire 3 gets the edge.   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.

The Vortex Venom optic gives me the confidence that I have a red dot sight that will perform reliably when I need it.   That is the bottom line on my red dot sight selection.

Making Your Decision – Your Needs and Preferences

Ultimately, your needs, expectations, and preferences should guide your decision about a red dot scope.  Do your due diligence, learn all you can, try them out if you can arrange it, and then decide.  In the meantime, be safe and shoot straight.
