Burris Fastfire 3 Review: Most Versatile Red Dot Sight With Great Value

As a buyer of a sight, you want to maximize value for your money.

Burris Fastfire 3 red dot is one of the lightest and most compact red dot sights come across on the market, giving you a great handling and balancing.

And if you thought that the light sight handles a highly-recoiling caliber poorly, you’re wrong. With as large a size of a cartridge as .50BMG, .500 S&W or a .460 S&W, recoil won’t be a put-off and a punishment during a long period of shooting using your handgun or shotgun.

Thanks to a chassis whose makeup is an alloy of bronze, stainless steel and anodized aluminum, the sight can withstand the harshest of recoils, and rain and snow can’t penetrate.

  • 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.

If you care more about an addition of each ounce to your hunting gear, consider one of the lightest red dots you’ll ever come across on the market.

Weighing 0.9-ounces (0.0255g) without a mount, Fastfire 3 is ultralight, convenient for long trek hunters.

More than that, the sight is extremely compact. Measuring 1.8-inches (4.5cm), the red dot is easy to handle and balance. Even so, extreme compactness and lightness don’t prevent it from handling recoil very well.

No need to worry about cartridges producing as high a recoiling magnitude as 1000 G’s. So, if you’ve a cartridge like .50BMG, .500 S&W or a .460 S&W, you can be sure the sight can withstand a long period of punishing recoil that it produces.

How so?

Materials as tough and shock resistant as an alloy of bronze, stainless steel and anodized aluminum contribute to resistance and toughness. In addition, they prevent water from penetrating the optics and vital components.

Optics quality at its price range is unbelievable. High-grade glass makes up the lenses.

Multiple layers of coatings with Hi-Lume technology and index matching sandwich the lenses to maximize light transfer in low-light conditions. These layers also prevent glares from irritating your eyes and obstructing your vision when sighting.

No matter where you position your eyes from the ocular lens, you’ll be able to see the red reticle clearly. Whether it’s a bright day or a dark night, the red dot remains visible.

Measuring 3-MOA across, the reticle is small enough for painting targets precisely at medium- and long-range distances. But a 1.07x magnification power, which a 21mm objective lens provides, limits your eye to close- and medium-range distances.

With the lowest magnification power, you’ve the widest field of view at your disposal. Your awareness of objects around you is unmatched, as you can aim with both your eyes wide open.

To make your close-range hunting more precise, you can customize the sight to an 8-MOA reticle. You can find 8-MOA reticle suitable for handguns and shotguns, as a larger dot covers far more of the overall are of target, enabling you to acquire targets much faster.

And so, eye relief is unlimited, but you must choose a comfortable position of your eye from the ocular lens to avoid injuries from a recoiling caliber.

Best of all, there’s no distance you’ve to worry about making corrections for parallax. As long as you’re able to see the reticle, all you need to do is to paint your target. Simple and fast.

As part of a T.M.P.R system, you can pair the sight with another sight, or mount it onto another sight, enabling you to adapt it to various ranges.

Consider pairing Fastfire 3 with compatible sights, such as laser and prism sights 332mm and 532mm for longer-range situations.

On the top of the sight is where you find a compartment for a CR1632 or a CR2016 battery, which has enough capacity to power dual sight systems. On the bottom is an extra compartment for a spare.

Battery life extends to 5 years (about 5000 hours), as a hood cover automatically switches off the sight after 8 hours of idleness, preventing power drainage.

And if you’re too lazy to make lots of adjustments, you’ll be happy with a sight, which allows you to regulate 3 brightness levels: low, medium and high.

Oh, brightness levels change automatically according to the environmental conditions, too! All that is attributable to a brightness sensor on the front.

Contributing to Fastfire 3’s awesomeness is the adaptability to almost any rail or base.

When you buy the sight, the manufacturer has already adapted the mount to a weaver or picatinny rail on your firearm, it doesn’t matter whether it’s a handgun, a shotgun, a pistol or a rifle. There are different ways you can adapt the mount to the rails.

Burris Fastfire 3 mount matches perfectly with a pistol system as a Glock MOS or an M&P C.O.R.E. But as long as your firearm is optics-ready, you’re good to go.

Nevertheless, don’t forget to match the length of mounting screws with your firearm. Fortunately, firearm manufacturers specify what screw lengths match with what mount.

And if you were expecting to find turrets and their annoying caps, there aren’t any. Instead, you’ve arrow buttons on the side and top of the sight for hold-off and holdover adjustments. Nor do you need to have some sort of Allen key or coin to rotate the dials.

You can see Burris Fastfire 3 problems when you have to remove the sight from the rail to access the extra compartment on the bottom.

While zeroing or sighting in can be a pain, that’s no longer the case with this sight. Detents are present on the sighting in adjustment, so, with each position, clicks are audible.

How to Mount a Burris Fastfire III

As long as your pistol, rifle or carbine has a weaver or picatinny rail, you can mount the sight.

If you’ve a handgun, a shotgun or a rifle, you may require a different mounting plate.

Luckily, Burris has adapted mounting plates differently to suit your rail.

How to Mount a Burris Fastfire III

Mounting the Plate on a Picatinny or Weaver Rail

  • On the right side of the mounting plate, there’s a clamp nut. Unfasten it.
  • On the rail of your firearm, attach the mounting plate by fastening cross screws.
  • Check whether the edges of the mounting plate match perfectly with the rail.
  • Press down the sight as you slide the mounting plate along the rail toward the muzzle of your firearm until you reach a distance where eye relief is most comfortable.
  • Fasten the clamp with a force of no more than 20-in-lbs.

Mounting the AR-F3 Mounting Plate

  • Use a cross bolt to attach the mounting plate on the rail.
  • To make the most out of field of view, slide the mounting plate toward the rear of the rail.
  • The packages comes with a wrench. Use it to fasten the nut with a force of not more than 20-in-lbs.
  • Using a Torx wrench, attach your sight on the mounting plate. Don’t use a force of more than 12-in-lbs to fasten the screws.

Mounting on a Glock MOS system of Your Pistol

  • Unfasten the screws on the slide plate.
  • Remove the slide plate from the system.
  • Ensure you keep the screws aside, because you’ll need them later on.
  • Glock package comes with an adapter set. Find it.
  • On the empty slot the slide plate left, fill it by attaching plate 01 using the short screws available in the package.
  • Now, place the sight on the plate 01 using by fastening all the locating pins.
  • Use longer screws you removed from the slide plate to attach the slide plate. You’ll need 2 lock washers.

How to Adjust Burris Fastfire 3

There are three instances when you need to adjust the scope:

  • Sighting in the point-of-aim.
  • Making hold-off and holdover.
  • Varying power for different brightness intensity levels.

Let’s have a look at each instance.

Sighting in the Point-of-aim

There are arrow buttons, dialing which amounts to making compensations for bullet drop (holdovers) and wind drifts (hold-offs). At a 100-yard distance, when you rotate the dial and hear a click sound, you’ve moved the point-of-aim by 1-inch.

You’ll have to hear clicks a maximum of 115 times (115-MOA) to move the point of aim 115-inches when correcting for holdovers.

On the other hand, the maximum number of times you’ll have to hear clicks when correcting for hold-offs is 86 times (86-MOA) to move the point-of-aim 86-inches.

When you zero or sight in at half the yardage (50-yards), point-of-aim moves by 0.5-inches. So, you need to make calculations.

Making Hold-off and Holdover

Relating to the point-of-impact adjustment, there are arrow buttons, which you need to turn. There are stops at either end of a hold-off (windage) adjustment button, though.

If you want to use the windage adjustment to lock movement of the elevation, screw it onto a stop.

Varying Power for Different Brightness Intensity Levels

On the left side of the chassis there is a power button. Every time you push the button, the brightness level varies. Four alternatives the sight provides you:

  • Automatic control. A sensor senses variation in light intensities in the environment, setting the brightness level accordingly.
  • High
  • Medium
  • Low

While the sight will switch off automatically after 8 hours when you forget. If you want to preserve battery, press the power button switch off the sight after use.

It’s important to note that the dot will blink twice each 5 seconds when battery life reduces to below 4 hours.

How to Zero a Burris Fastfire 3

When you make corrections for bullet drop and hold-offs, you’re essentially moving the point-of-impact.

  • Choose a maximum distance to shoot at target, say, 15-yards. You’ll need to bore sight and choose a cartridge.
  • Fire three shots at the bullseye and take note of the center of the groupings. Take note of how many inches from the bullseye each bullet is lodged.
  • Move the point-of-aim move toward the center of the groupings as you make relevant adjustments for windage and elevation. In this case, you need to move point-of-aim by 15-inches at 15-yards.
  • Fire three shots again. Take note of the groupings again.
  • If shots are precise, you’ve zeroed or sighted in your red dot sight.

Final Thoughts

Fastfire 3 is one of the lightest and most compact sights you’ll ever come across on the market. And that counts greatly in your favor, as you can handle and balance it easily.

Quality of optics is too good to be true at this price range.

When you talk about multiple layers of coatings with index matching to maximize light transfer, you get the impression of a high-end or military-grade sight. But is it?

If you’re a hunter and you’re looking for a maximum value for your money, Fastfire 3 has what it takes. Just as any other red dot, target acquisition is fast and straightforward. Sighting in is nearly hassle-free.
