Vortex Spitfire 3x Review: Vortex spitfire 3x prism scope has Just Enough Features for Your Civilian Defence Needs

If you don’t mind digging deeper into your pocket for a higher-quality optic, which leverages the strength of both a red dot and a scope, you’re on the same boat.

If also you don’t mind about the extra weight, Spitfire is a great go-to. Law enforcers, military personnel and security officers would find great delight in the prism scope.

After all, why spend more, and you have a scope, which has a military grade optic at a much lower price.

All you need to do to qualify is to have an AR15 rifle with a picatinny rail and a 5.56×45 or a .223 Remington cartridge.

Spitfire gives you unmatched accuracy when you sight it in at a close- or medium-range distance.

Spitfire has breath-taking features; surely, it should belong to a higher price range.

So you think. For civilian use, the scope has just enough features for you to avoid wasting your money on unnecessary ranges.

Of Vortex Spitfire Prism Scopes, the prism scope stands out.

Vortex Spitfire 3x Review

If you own as lightweight a rifle as AR15, then you’re in luck. Vortex built Spitfire specifically for AR15, but you can fit the scope to any rifle for modular sporting, bullpup or SCAR.

Talk of maximum accuracy at the close- and medium-range for a rifle that’s able to stabilize as light weight of bullets as a 5.56×45 or a .223 Remington round, and you’re reading from the same page.

For maximum performance, the length of the barrel of your rifle must be 16-inches.

Use a round whose weight is 55-grain to maintain a flatter downrange path, as a shorter barrel sacrifices speed for accuracy.

Spitfire can serve you well when defending yourself, your property or your country.

A hybrid of a red dot and a scope, the budget prism scope leverages the unique strengths of both. Unsurprisingly, the resultant – a prism scope – has more superior optics and costs more than any ordinary red dot or scope.

Multiple layers of coatings of anti-glare materials minimize light wastage. Vortex anodized the finish to give the chassis anti-glare properties.

Magnification power is fixed at 3x, giving you a wide field of view at close ranges. At 100-yards, the width of field of view is 31.5 feet (10.49-yards).

Unlike red dots and scopes, the best 3x prism scope on the market has four intersections at different points on a single line running somewhat halfway through the field of view: reticle EBR-556B, resulting to crosshairs.

Each crosshair represents a maximum range of distances to which you can make compensations for a bullet drop.

The first crosshair whose size is 7.6 MOA is the main crosshair. You can use it to make a holdover for distances between 100- and 200-yards.

The second, third and fourth crosshairs have a size of 5-, 4- and 3-MOA respectively. They stand for holdovers at 300-, 400- and 500-yards, respectively.

One minute of angle (MOA) is equivalent ¼-inches at 25-yards. That means you’ll hear a click when you move the point of aim toward the bullseye by ¼-inches. The maximum number of clicks you’ll hear when turning windage and elevation adjustments is 120.

Inside of 100-yards, don’t worry about making corrections for parallax.

Vortex embedded the reticle on the prism. And so, despite light conditions, the etching is visible. You don’t need battery power to light up the reticle.

And this can count in your favor, because when the battery runs out, you can still move the point of impact, despite light conditions.

Even so, you must use the ocular lens to increase resolution – make the reticle’s focus sharper.

For maximum comfort, and to avoid recoil from injuring your face, place your eye 2.8-inches from the ocular lens.

But if you decide to use up your battery to illuminate the field of view, there are five ways you can adjust brightness. The color of reticle’s brightness can be red or green.

Even if you keep brightness at maximum (5), CR2032 battery can last up to 250 hours. If you keep brightness at moderate levels or lower, life increases to 3000 hours.

Coming with a mount, you can vary height between a Co-Witness low of 40mm and 30mm, which requires you to remove the riser.

What’s more awesome, you can clamp the sight to your rifle alongside another sight, as AR15 platforms have two picatinny rails.

Spitfire can withstand recoil, as its chassis is made of shockproof materials.

Inside the main tube is a purging of nitrogen, so when you move across variable temperature conditions, optics won’t fog up.

Machining the surface to be uneven, the scope is rough and tough, so you won’t lose grip when handling. Adding to ease of handling is compactness, yet the quality of optics remains high.

Objective lens’s diameter is 32mm. Measuring 5.5-inches (13.75cm) across, Spitfire isn’t nearly as compact as just any other red dot or scope.

Besides, if every ounce counts, then it can be quite a pain as an addition to your gear. Weighty as it is, 15.4-ounces (437g) can feel like more burden.

Furthermore, lenses and turrets wear O-ring seals, which prevent water, dust, and debris from entering inside.

Lens and turret caps can be a big turnoff, as they wear out easily.

How to Mount Vortex Spitfire 3x

The manufacturer has set mounting height at 40.4mm – a distance between the platform’s surface and the center of the prism.

Suitable for the clamp to an AR15 picatinny rail, the height is low – 1/3 Co-Witness.

But if you want a lower height (30mm) than what’s already low, remove the riser and the clamp of the platform.

How to Mount Vortex Spitfire 3x

You need shorter screws, which, luckily, come with the package. Use the screws to reinstall the clamp once you remove the riser. You need to lock threads temporarily in place using a compound to install the screws.

Here’s how to mount a Spitfire:

  • Ensure the brightness adjustment dial faces you as you align the scope.
  • Unfasten the two hex nuts at the platform and clamp the scope to the platform. Ensure recoil lugs remain in the grooves of the platform.
  • Verify whether there’s a full attachment between the platform and the mount by pushing down the scope as you move it forward. Fasten the hex nuts of the platform in a way to give them torque. Position the scope from the muzzle such that you’ve more than 2-inches of eye relief. You don’t want to place your eyes too close to the ocular lens, as you risk injury. Before you fasten the mount onto the rail, ensure the field of view is fully visible.

Vortex Spitfire 3x Adjustment

Talking of adjustments, there are lots to go around. Consider the following instances when you need to adjust your scope:

  • When installing the battery
  • Controlling brightness intensities
  • Focusing the sharpness (resolution) of the reticle.
  • Compensating for bullet drop and wind drifts

Let’s take a look at each briefly.

Installing Battery

  • Use a screwdriver or a coin to remove the compartment of the battery.
  • Insert and align the battery. Ensure the negative side (-) faces downward before you replace the cover.
  • As you replace the cover, verify whether you screwed it down completely in place with the O-ring seal.

Controlling Brightness Intensities

  • Turn the dial either way.
  • Once you choose either green or red numbers on the dial, turn the dial such that the color you selected faces you. It’s important to note that once you complete your task, rotate the dial back to 0 to avoid wasting battery.

Focusing Reticle Sharpness

  • Stare at the sky or blank through your Spitfire. Avoid staring at the sun directly through a scope to avoid damaging your eyesight.
  • Rotate the dial of the ocular lens either way to find the crispiest reticle image.
  • Ensure your reticle is in focus before your eyes and brain begin to make compensation. We recommend you make adjustments fast.

Compensating for Bullet Drop and Wind Drifts

  • Open the flip caps.
  • Use a screwdriver or a coin to turn the dial.
  • Follow the arrow labels on the dial for the correct direction.

If you’re zeroing at 50-yards, and a shot you fired has a bullet lodged 1-inch to the left of the bullseye, you’ll hear 4 clicks to move the point of impact to the right toward the target by turning the dial anticlockwise.

How to Zero or Sight in Vortex Spifire 3x

How to Zero or Sight in Vortex Spifire 3x

Once you clamp the scope to the base of the rail, it’s time to zero.

First off, you must see through the bore of your rifle’s barrel to determine the maximum shooting distance and cartridge. Afterward, you can zero your scope at the range you determine during bore sighting.

We recommend you bore sight at a close-range distance of between 25- and 50-yards. Vortex has an instruction manual for how to use a bore sighter. Alternatively, you can remove the bolt from your rifle and sight visually through the bore.

See Through the Bore of the Barrel First

  • On a rest, place your rifle squarely and extract the bolt.
  • See through the bore of the barrel as you position the bullseye inside.
  • Once you center the bullseye, make compensations for bullet drop and wind drifts to align the crosshair with the bullseye.

Zero or Sight in at a Range you chose

  • Once you finish seeing through the barrel, shoot the target once or twice at the distance you chose. The groupings you get at this stage enable you to approximate your target. Make adjustments for wind drifts and bullet drop again to move the point of impact at or near the bullseye.
  • Now, shoot three times, and take note of the center of the groupings this time.
  • With reference point being the center of the groupings, repeat the process of compensating for wind drifts and bullet drop. Use arrows to make reference to the direction which you wish to turn the dial.
  • Again, fire three shots just to be sure. If not precise, repeat the procedure for more precision.


If you’re willing to fork out more money for a hybrid that leverages the strengths of a red dot and a scope, the Spitfire is your go-to choice.

In our vortex spitfire review, you’ve learned about the features, specifications, benefits, and drawbacks of the sight.

While Spitfire gives you a wider field of view at 100-yards than either a red dot or a scope, a 3x magnification limits your ability to be aware of objects around you. More than that, Spitfire is longer and heavier than any red dot.

Hence, it’s less compact.

What you can leverage is its excellent ability to leverage recoil and generous eye relief for distances inside of 100-yards.

Just like its counterparts, Vortex has anodized the chassis and added multiple coatings to maximize light transfer.
