Burris Fastfire 3 vs Vortex Viper – Which Riflescope Goes the Extra Mile?

Burris Fastfire 3 vs Vortex Viper

Scopes don’t usually come with their custom-designed mounts but one of these riflescopes stands out from the pack. Which between the Burris Fastfire 3 and the Vortex Viper riflescopes goes the extra mile? 

My wife truly appreciates all my hobbies and last Christmas, she surprised me with a new hunting riflescope: the Burris Fastfire 3. Out of all the gifts I have gotten from her, I must say this is the best yet.

Knowing that she isn’t a hunting buff like myself, I am still puzzled at how she knew to select such an amazing riflescope. True to her nature, she swore never to tell me how she came across this masterpiece and I rested my case by settling on the idea that it was just a lucky guess.

So, I took it into the hunting range to compare it with my other favorite riflescope; the Vortex Viper.

Burris Fastfire 3 vs Vortex Viper – How do they compare?


The Burris Fastfire 3 scope has the Ballistic AR second focal plane reticle that provides a precise platform for measuring distance and determining target size. It features ½ MOA hash marks across the horizontal crosshairs and the lower level of the vertical crosshairs.

The reticle is illuminated in red and together with the red dot finder, they maintain the point of impact and make your shooting higher precision. The lenses are fully multi-coated providing brightness and clarity with long durability.

Vortex Viper is a first focal plane scope which means the reticle can be used effectively at any range and magnification. The fully multicoated XR lenses have extra-low dispersion elements and these give high-resolution imagery with great color fidelity.

The reticle is illuminated, glass-etched, and has large and small hash marks label with MOA values and dots for windage adjustments are on the bottom of the reticle system.

Burris Fastfire 3 clearly beats the Vortex Viper because even you will never lose your point of impact regardless of light conditions.  


The turrets on the Burris Fastfire 3 are capped and making adjustments can be done by hand and it maintains the zero hold. It is a close combat scope with ½ MOA per click and they work very smoothly with only a little slop to them.

The left side of the Vortex scope has parallax adjustments from 50 to 100 and into infinity with ¼ inch MOA adjustments. The turrets are nicely built and have aggressive texturing with audible and tactile clicks with labeling up and down or left and right to guide your direction in inches.

Turrets on Vortex are better because they have ¼ inch MOA adjustments that are more accurate than the ½ inch adjustments offered by Burris.

Burris Fastfire 3 vs Vortex Viper – A Comparison Overview 

Burris Fastfire 3 Review 

This scope is a combination set with all parts and added features such as a Picatinny rail mount and a red dot that makes it super convenient for quick mounting at no extra cost. Torque rings are easily manipulated and can be taken out for adjustments.

The red dot side has a battery that can run for hours. The screws for the red dot adjust for 1MOA and itself is a 3MOA Dot at 100 yards. The illumination settings for the red dot are high, medium, low, and off and it turns itself off after 8 hours of inactivity.

The eyepiece of this scope is built to be fast so it has a very coarse thread that is very smooth and it has a nice texture. The throw lever can go into any of the slots available between 1-6 working seamlessly.

This is a true low power variable optic with close-quarter combat, illuminated reticle, the ranging marks underneath for windage and elevation. It also features a true 1-power with a wide field of view.

Has positive click adjustments that are quite audible. Provides a CRS zero stop that helps get you back to zero though it is tricky to set up the first time. Windage is smooth but has no lock system. The left side of the scope has parallax adjustments from 50 to 100 and into infinity.

The turrets are nicely built and have aggressive texturing with audible and tactile clicks with labeling up and down or left and right to guide your direction in inches. All the clicks are ¼ per 100 yards and hold zero perfectly by using the CRS shims which is their unique selling point.

The parallax adjustment is clearly labeled. The reticle is illuminated at the center crosshairs and hash marks which allows for precise shots in the dusk or dawn. In between the brightness settings is an off position that limits the number of turns you need to make when switching in between the 10 settings available.

Burris Fastfire 3 has a classic Red dot finder that works in tandem with its illuminated reticle. Combined with its wide and long field of view, it makes for the ideal hunting scope for mid to long-range hunts.

Given its longer range of eye-relief, higher range of magnification, and its larger objective lens, the Vortex Viper is much more capable of light gathering capabilities and is more comfortable to use.

Final Verdict: So, which is better? Burris Fastfire 3 or Vortex Viper?

Burris Fastfire 3 is better than the Vortex Viper. This is because it goes the extra mile to provide its users with a complete set up that includes a red dot focuser and mount rails that can be installed on any rifle type you may own. Whether you are mid to long-range hunting, you can count on its precision in any light conditions.


Will the Vortex Viper be okay on a .416 Barrett cartridge?

Yes, with the right mounting hardware you should have absolutely no problem with this heavy-duty scope. It is built and tested to withstand the recoil, shock, and vibration of most rifles.

Does the Burris Fastfire 3 come with flip covers?

Yes, it does. It comes ready with the removable flip-up covers that are adequate in size and quality to keep your lenses in great shape. Plus, you won’t have to worry about losing them.
