Sightron is an American based company which produces its scopes mostly in Japan and Philipinnes. This particular product was made in the Philipinnes. Delta Optical on the other hand is based in Poland. The tested Titanium was made in Japan. This two scopes  both have variable magnification from 6x to 24x with the lens diameter of 42 mm and the parallax is placed on the objective. With their capped turrets they are mostly suitable for sport shooting, like the .22 benchrest and other .22 hunting disciplines. They are an excellent choice for precision competition rifles up to 300 m away. Further away it is impossible for compensation to set the turret as you run out of clicks.


Size and weight:

[table id=12 /]
Sightron is a bit bigger, bulkier. They weight almost the same, with a minimal difference of 2 grams. Both have a one inch main tube. The knobs are rigid on both scopes, which makes it a bit harder for gentle hands to operate. The products feature a lockable diopter on the eyepiece. Sightron offers a substantionally more precise setting of the parallax and is more sport shooter oriented.

Optical properties:

Both scopes offer similar properties with similar FOV (at least on paper, on the test  Sightron performed much better). After we had tested both products we analyzed the data collected and here are the results: regarding central sharpness Sightron was chosen as better by 4 persons compared to 3 for Delta. Edge sharpness was different as Delta got the majority with 5 votes out of 7. When it comes to eye-box Sightron again took the upper hand as it received 4 votes compared to 3 for Delta. They differ most at the tunnel effect where Sightron won 6 out of 7 votes. When we compared the products overall we came to the conclusion that the SII is better than Titanium 5:2. Altogether Sightron won 21 (out of possible 35) and Delta received 14 (out of 35).

Reticle properties:

[table id=14 /]
Of the tested models both had Mil-Dot, however I prefer the reticle on the Delta 6-24×42 as it is thinner, more modern in design. Otherwise, they are both placed in the second focal plane with no illumination. Sightron offers more different reticle styles to choose from. A very good reticle for the sport shooters is the T-dot, but it was unfortunately absent on this featured test. Because they are both SFP rifle scopes there is no practical reason for them to have a Mil-Dot cross, as it is very hard to set the proper magnification at which it is useful to use its compartments / divisions. Regardless on what was mentioned above the reticles are thin enough to allow the shooter to precisely hit the target.


Turret properties:

[table id=15 /]
The cap covers on the Sightron are not as well made as the ones on the Delta. Also the material chosen for the button axis on the Sightron is of questionable quality, as we’ve seen a lot of scratches (on a brand new product) on the silver surface of the knob. It does not affect the operation capabilities of the product but it does deteriorate the aestatics of the scope. Other than that, the clicks are firm and crisp on both products and also audible. We did not recognize big differences when it comes to turrets. Both delivered about the same, the main difference is that Sightron has great reputation for perfect tracking. We did however not tested tracking on any of these two scopes so we can’t make a direct comparison.

To say something about the turrets: SII has bigger sized turrets which boast a better grip and louder clicks. The SII turrets can be zeroed while the Titaniums can not. The SII only has 8 MOA per turn, which means that the clicks are bigger and its easier to know where you are positioned. It is surprising that none of the tested products had a 10 MOA per turn as it is the easiest to calculate. Both rifle scopes have 50 MOA total turn which translates to about 300 m of effective range.

General properties:

[table id=16 /]
Both scopes offer a 10 years warranty. They are very similar in build quality but the Sightron is almost 200 euros more expensive and for that extra amount of money you get within your package a sunshade, cleaning cloth, user manual and reticle properties manual. With Delta you have to buy the sun shade separately.



All in all this test has shown to us that Sightron is optically superior to Delta, but is at the same time heavier and more robust. Not to mention it costs a whole 210 euros more. For that money Delta did a superb job as the scope is still very well made. The build quality is good. The parallax is not as finely tunable as it is with the SII, so for that reason we would recommend Sightron for sports shooters. The scopes are best fitted with accurate, smaller caliber rifles such as the .17 HMR, .223 Remington .22 lr. All in all Sightron is a better, but at the same time more expensive choice.


We would like to thank Optics Trade for letting us use and test the above mentioned products. We also thank them for letting us use their videos.

This featured test is impartial and we always try our best not to prejudice and favor one product over the other. Our team of enthusiasts who tests these products and writes these articles is doing it from dedication, as rifle scopes are our big passion. We also feel a great amount of joy and satisfaction when we know that we have contributed and shared with you our experiences. We try not to be bias and try to be as accurate as possible when interpreting our sightings. We will do our best to described things as they really are.

How the testing is done:

Our team comprises of two enthusiasts who write the articles for hobby and our very helpful unbiased friends who help us make the evaluations, such as the optical characteristics. As we are volunteers/enthusiasts we are not always present in the same numbers. Our ranks can fluctuate from 5 to around 8 people at the time of a test. Other than the two of us who are responsible for writing the articles our friends have almost zero experience in rifle scopes. They have no prejudice and are as such perfect for our objective observations. None-the-less we always try our best to hide all the labels that can give away the products ID. For that reason we mount the rifle scopes in parallel on a special stand and cover them so the brand names are not visible.

We accurately fine tune the parallax on all the testing products for observing trees and buildings at 350 m and each person sets the diopter for their specific needs.

After we are sure that the test can be done without preferations we ask our volunteers to test the following parameters:

  • Central sharpness – subjective impression at 10x,
  • Edge sharpness – subjective impression at 10x,
  • Eye-box,
  • Tunneling effect at low magnifications,
  • FOV – subjective impression at 10x

    You should chech the data. I believe you published Sightron results under Delta (and vice versa) in the Optical properties table.
    Apart of that, all-in-all a good and quality review.
    Keep on doing good job!
