About the Sightron company

The company Sightron is already quite an old company, with almost 30 years of existence. It was founded in 1993 in North Carolina, United States. The parent company of Sightron, Kenko-Tokina, is located in Japan and has an even longer tradition of optics manufacturing, dating back to 1957.

Sightron owns two production facilities; one is located in Japan and the other is in the Philippines. All of their products are made completely in-house; they do not outsource any of their production. At the Philippines facility, only entry-level and midrange products are made, while only premium products are made in Japan.

Sightron SIII series of riflescopes are made in Japan. Sightron’s guiding principle is that their products are not overly feature-rich, but they have excellent quality, especially optical quality.

This is exactly why sports shooters like Sightron’s riflescopes. Especially shooters who aren’t concerned with the appearance of the scope but do care about optic quality and how their target image appears when looking through the scope.

Overview of Sightron SIII 6-24×50

In this article, I will review two Sightron SIII 6-24×50 riflescopes: the tactical and target models. Both of them have the same magnification range, spanning from 6x to 24x. However, the main difference between these two scopes lies in the turrets: one has tactical turrets and the other has capped target turrets. This is also the only visible difference on the outside.

Another difference between these two scopes is that one has the reticle positioned in the second focal plane and the other has the reticle positioned in the first focal plane; however, more about this will be discussed later.

Both of the riflescopes are from the SIII series of riflescopes, which is a premium line from Sightron. The SIII series of riflescopes from Sightron is renowned for its price-to-performance ratio; you get a lot for what you pay. All scopes in this series are the target or benchrest rifle scopes, and there are also a few tactical ones.

Riflescopes from the SIII series:

Optical performance

Sightron SIII 6-24×50 features a magnification range from 6x to 24x. The scope features four times the zoom factor and a magnification lens diameter of 50 millimeters. The scope is also quite bright at dusk and dawn.

The field of view on the smallest magnification is 5.37 meters at 100 meters. On 24x magnification, it’s 1.3 meters at 100 meters. The scope has no tunneling effect, and eye relief ranges from 91.4-96.5 millimeters. I noticed that the eye relief is very forgiving; you can move behind the scope and still have a clear picture.

Additionally, 6-24×50 riflescopes also feature a fast focus for diopter setting and a nice forgiving eye box meaning that your eye doesn’t need to be in the ideal alignment all the time. Even if you shoot a lot, your eyes will not be as fatigued. This is also the reason why these scopes are so popular among sports shooters. There is however some discrepancy between 6x and 24x magnification. With 6x magnification, you get greater clarity than if upscaled to the highest magnification.

This image is simply remarkable, particularly when you consider the price. Not only does it have extraordinary resolution and full-frame clarity, but also has astonishingly precise color accuracy.

All optical components in the SIII long-range scope feature seven-layered coatings.

I believe no other scope in this price class can match Sightron’s optical performance.

Physical properties

Sightron SIII 6-24×50 features a 50mm objective lens and has an outside diameter of 58 millimeters. This external measurement is critical for calculating the scope mount’s height or attaching night-vision or thermal clip-on devices if you plan to use the scope for hunting as well. Make sure to double-check this dimension when selecting the appropriate clip-on mount.

The scope is completely made of metal, with only a rubberized part on the ocular. It is completely shockproof and can be mounted onto very strong recoiling calibers, such as the 50 BMG. It is nitrogen purged, allowing it to be used in very cold environments without internal fogging on the lenses. Furthermore, it is completely waterproof, so you don’t have to worry when you’re out in the rain.

The size of both scopes (tactical and target model) is 380 millimeters, and they are very lightweight. They weigh only 690 grams, which I think is quite light for such a scope.

SIII 6-24×50 also has a precise track mechanism for accurate tracking. Most sport shooters would tell you that Sightron scopes have one of the best trackings for the money. In their price range, they’re virtually unique in having this characteristic and you can find many videos proving their superb tracking on YouTube.

Eyepiece design

As previously noted, the only rubberized portion of this riflescope is its ocular. It’s designed with a European-style eyepiece and adjustments that are both smooth yet firm to ensure they won’t accidentally be shifted when you stow away your scope into your backpack or shooting case.

The magnification ring

The smooth exterior of the magnification ring provides a secure grip, even when wearing gloves. With 180 degrees of rotation from the lowest to the highest power setting, you can effortlessly adjust your magnification for any task. The magnification ring is designed with one slightly larger ridge that acts as a small throw lever.

No illumination system

The Sightron SIII 6-24×50 scopes, with either capped target or tactical turrets, are crafted for use exclusively during the day – they do not offer reticle illumination.

However, I believe that even in a tactical scope, this isn’t an issue. Not to mention Target models which will never need illuminated reticle. The fact that the reticle is non-illuminated speaks volumes about Sightron’s philosophy. They rather invest money into an optical performance that is always needed, than in reticle illumination that is needed only very seldomly in the rifle scopes for this purpose.

Parallax adjustment

The parallax adjustment on the target model is identical to that found on its tactical counterpart. It is located on the right-side turret, with a parallax range of 40 meters to infinity in an approximately 180-degree turn. On some occasions, we’ve noticed that despite Sightron claiming that the parallax can be adjusted from 40 meters onwards, they can be focused even closer.

I would prefer a bigger turret with more rotation so that I can more easily fine-tune the parallax. However, based on what I have tested, it is good even with 180 degrees of turn. You can easily fine-tune the parallax to your target.

Tactical model

The Sightron SIII 6-24×50 tactical model features un-capped tactical turrets, three different reticles to select from in either the first or second focal plane, and 0.1 MIL or 1/4 adjustment per click. Those looking for an extra edge may also choose to add on the optional zero-stop function as well.

Tactical model reticle

When ordering the SIII 6-24×50 scope with tactical turrets, you have a choice of having the reticle located in either the first or second focal plane.

There are three different reticles to choose from:

  1. MOA-2
  2. Mill-Hash
  3. Mill Dot

The MOA-2 reticle comes in the first or second focal plane, while the Mill-Hash is only available in the first and a MillDot reticle is only available in the second focal plane. As I mentioned before, none of the reticles are illuminated.

Elevation turret on the tactical model

Adjustment per click on the tactical model is either 0.1 MIL or 1/4 MOA; you can choose between these two options.

0.1 MIL adjustment per click

If you opt for the first focal plane reticle with 0.1 MIL adjustment per click, every single click equals one centimeter at 100 meters away. One full rotation has a total of 5 MILs in elevation – that’s 50 centimeters at 100 meters. The entire elevation is 23.3 MILs. If you select an 0.1 MIL adjustment per click on the second focal plane scope, the full elevation range will be 25 MILs.

1/4 MOA adjustment per click

Deciding to go with a 1/4 MOA adjustment per click on the FFP scope will grant you 80 MOA of elevation range, whereas selecting an SFP riflescope with 1/4 MOA adjustment per click offers you an even higher 100 MOA total elevation range.

Clicks on the tactical model

The clicks on this turret are so positive and tactile that you can both feel and hear the distinct click for each adjustment. Plus, the intensity of each click makes it unlikely to move accidentally – a feature I particularly appreciate in an open turret design like this one.

Moreover, with only 5 MILs in one revolution and 23 MILs in the entire revolution, this is a multi-turn turret that allows you to make multiple revolutions both clockwise and counterclockwise.

Tactical turrets

Turn indicator on the tactical model

Under the turret are fine, white lines, which act as the turn indicator. What I noticed is that the zero is not at the bottom of the turret. Therefore, the lines are mainly designed for mounting the scope without any inclination. If you choose to mount the scope with an inclination to shoot at longer distances, however, the lines will not match the rotation you are in.

So, if you mount a scope using a 20 MOA base, your zero would be approximately where the line with number one is. Thus, the first revolution would be at zero, the second at one, and the third at two. Therefore, I think this is worth mentioning.

Zero-stop feature on the tactical model

There is an option to choose the tactical model with or without a zero-stop feature. The models featuring a zero-stop function have a large ring located under the elevation turret, which can be screwed up to the turret. Then, small screws on the side of the ring are used to lock it in place. It is a simple and easy-to-operate design.

Resetting the elevation turret to zero on the tactical model

The elevation turret is easy to set to zero. You just have to unscrew the screw on the top of the elevation turret, and then the whole turret will rotate freely. Rotate the turret so that the zero is facing forward, and then tighten the screw; when done, the zero will already be set.

Windage turret on the tactical model

The windage turret is practically the same as the elevation turret. The adjustment per click on the windage turret is also equal to that on the elevation turret, and the setting of the zero position is also similar. Like the elevation turret, the windage turret is also of a multi-turn type.

One disadvantage I find in the windage turret is that all numerical markings are only visible from one direction. Therefore, if you rotate it to the right side, counting clicks is necessary as there is no indication of numbers for this orientation. It would be much easier and more convenient if numerals were made available on both sides of the turret.

Target model

The Sightron SIII 6-24×50 target model features capped target turrets and a Mil Dot reticle positioned in the second focal plane. Adjustments per click is 1/4 MOA, and there is no zero-stop function available.

Reticle in the target model

The reticle is in the second focal plane, which means the reticle subtension does not change as magnification is increased – the reticle stays consistent.

At a distance of 100 meters, the central dot for aiming is merely one centimeter thick, and all dots and small lines are always visible. The reticle was created this way – all the dots and small lines are still visible even at the lowest magnification. The same is true at the highest magnification since there are no lines outside of the minimal field of view (which happens at the highest magnification).

Elevation turret on the target model

The target model features a capped elevation turret; the elevation turret on the model is of the multi-turn type. The clicks are perfect; they feel very nice. The target model is only available with the reticle in the second focal plane and with 1/4 MOA adjustment per click. The total elevation range is 100 MOA, and in one revolution the target model has 15 MOA of elevation.

Turn indicator on the target model

Like the tactical model, the target model also features fine lines under the elevation turret which act as turn indicators. Similarly to the tactical model, if you mount the scope with inclination, the lines will not match the rotation.

Resetting the elevation turret to zero on the target model

The zeroing process is uncomplicated and straightforward. To adjust your zero, you’ll need a small hex wrench and will have to unscrew the three screws on top of the elevation turret. With these loosened, the turret can swivel freely; turn it so that “zero” is facing forward then tighten those same screws. You’re all set – your zero has been properly adjusted.

Windage turret on the target model

Boasting identical adjustment per click, the windage and elevation turrets on this target model are equally simple to zero. Both turrets are also of the multi-turn type.

Notably, the windage turret of the target model experiences a strikingly similar issue to its tactical counterpart – with numbers that only ascend in one single direction. I’m sure most would concur that it would be beneficial if there were another set of figures that ascended in the opposite direction.

Pros

Let’s wrap up with the highlights. What positives can we take away?

The Sightron SIII 6-24×50 scope is incredibly well made. Every component from the turrets to the magnification ring is solidly constructed, with no wobbling or loose parts in sight.

The optical quality of this product is exceptional, especially for its modest price point.

Both clicks on the turrets, whether they be tactical or target-oriented, will provide excellent performance that rivals even more costly riflescopes. They make an audible and tactile sound when rotated and can easily be zeroed.

I am very pleased that the tactical turrets can be provided with a zero stop as an optional feature.

Not only are these scopes lightweight, but they offer unbeatable value for money. You can also choose from either the first-focal-plane or the second-focal-plane reticles, as well as select between MIL and MOA measurements, making them incredibly versatile.

Pros summary:

  1. accurate tracking
  2. good build quality
  3. great optical performance
  4. tactical and target turrets
  5. SFP or FFP reticle
  6. zero-stop option

Cons

What areas need to be improved upon? For optimal use, I believe that offering the scope with illumination would be a great addition. Due to its magnification and objective diameter, this model could also serve as an ideal hunting tool – making an illuminated reticle a desirable option in my opinion.

For the parallax, I would appreciate a larger turret for better accuracy when making fine adjustments.

Lastly, the markings on the windage turret would be much improved if they had a two-directional design instead of only going one direction.

Cons summary:

  1. no illumination
  2. parallax
  3. windage turret has markings only in one direction

Final thoughts 

The Sightron SIII 6-24×50 is a top-level scope from Japan that offers maximum precision. With its 10-year warranty, solid construction, and optical quality, this product provides excellent value for money.

However, to get the most out of it certain areas need improvements such as illumination, parallax adjustment, and windage turret design.

When comes to build quality the Sightron SIII 6-24×50 does not disappoint. All components from the turrets to the magnification ring are solidly constructed giving you peace of mind when using this scope. The optical performance is also exceptional considering its modest price point.

Furthermore, both clicks on the turrets offer great performance whether they be tactical or target-oriented making them very versatile in terms of use cases. As an optional feature, you can even get a zero-stop.

Ultimately, I believe the Sightron SIII 6-24×50 scope is perfect for target shooting and more than suitable for long-range hunting. If you’re looking to take part in tactical competitions like PRS or a similar event, then the first focal plane model should certainly suffice too.

For those who search for features like illuminated reticlesmechanical turn indicatorsturret locking, and, a bigger elevation range there are other options on the market. In the same price class, you will need to make sacrifices in the field of optical quality. If you wish to keep the same optical performance but would still need all mentioned features, then you will need to invest substantially more.
