Sightron STAC riflescopes | Optics Trade Debates

Hello and welcome to another episode of Optics Trade Debates. Today, we will talk about the Sightron STAC riflescopes. We already made a video on the SIII series, and now, here is the one about STAC.

There are 6 models available, so let us discuss some features that unify these models. In the previous debates, we already mentioned that the SIII is the workhorse of the Sightron – the most popular series, and the STAC is slowly catching up regarding popularity. In the numbers of sales it is seen that STAC is becoming more and more popular and in the future, it will share the throne with the SIII regarding the sales numbers for Sightron.

All of the scopes are made in the Philipines and not in Japan, like the majority of the Sightron scopes. They all feature a 30 mm tube, and a bit bigger zoom factors than the SIII. There is the 1-7 wide-angle model with an illuminated reticle, the 2-10x32 model with a 5x zoom, the 3-16 model, which has a little bit more than a 5x zoom and a 42 mm lens (which is very popular). Then there is the 4-20x50 – again, it has a 5x zoom, and the 2.5x17.5 – 6x zoom. There are different zoom factors that are always higher than 5. So, compared to the SIII model, they have a bigger zoom factor.

Historically speaking, the 1-7, and the 2.5-17 were the first models introduced in this line in 2012, so quite a long time ago. The main growth of the whole series, especially in terms of sales were the 2-10x32, the 3-16x42, and the 4-20x50 – they lifted up the sales. Even though the models mentioned should be tactical, they do not include real tactical features like the exposed tactical turrets or reticles in the first focal plane.

The clicks are ¼ MOA, so this -TAC in the name is a bit misleading but still, if you are searching for a scope below 1000 €, the optical quality is quite convincible. The brightness and the color fidelity are great. The field of view is not as good as on the other, more expensive Sightron products, which is expected. What is also very good, is the eye relief; it is extremely long, so you are able to use them of powerful rifles.

What was a great delight for us was in 2019, they finally made a tactical STAC, the 4-20X50. Just by looking at it, it can be seen that it stand out of the STAC series – it has exposed tactical turrets, and the zero stop function (which all the other models lacked). The zero stop is the same as on the other SIII models, so a ring around the turret where you set how long can it go. The click value is 1 cm on 100 m, and MIL suspensions on the reticle, so it is a MIL/MIL scope. IT is also a first focal plane scope and is packed with features.

The only thing missing compared to more expensive tactical scopes is the locking function for the turret and the mechanical turn indicator – which is normal for this price point, as the scope is priced even under the SIII series. All the scopes in this line have an integrated, foldable throw lever, except the “hunting models” (the 1-7, and the 2.5-17.5). It is a nice feature and makes the scope easier to use.

The scopes perform well – they track amazingly, offer great resolution, colors, a good light transmission rate. The field of view could have been a bit better – there is a bit of tunnel vision. But still, like all Sightron products, they feature a great price for an even greater quality – they do not invest in marketing, but only wish to produce the best possible quality for the price that the customer is paying.

The 2-10, 3-16, 4-20 offer the duplex reticle, which is used for hunting. With tactical reticles (MOA-2, MOA-3 style reticles) the main lines are quite thin for this price point, which is one of the reasons why they are so popular. Sightron kept the name STAC, but clear difference can be seen regarding the philosophy of the scopes if comparing the 2-10, 3-16, and the 4-10 to both of the older models: the 1-7 (wide-angle), and the 2.5-17.5. The latter two can be ordered with a low hunting turret (capped, but not meant for target use), and both have an illuminated reticle. You can choose either a Hunting-4 illuminated or an MOA-2 illuminated reticle. In both cases, the dot is a bit bigger and the 2.5-17.5 comes very close to being day-time usable. The 1-7 is a bit more powerful and not day-time usable if the sun is shining.

With the 1-7, and the 2.5-17.5 models, the optics are amazing; you get a wider field of view; the 2.5-17.5 does not suffer from any tunneling, the resolution, and the light-transmission rate are great. The 2.5-15.5 works best for hunters who want to have a cheaper scope than the premium European scopes You have everything – illumination, capped low-profile turrets, an extreme zoom factor, a wide field of view, and great optics for the price point of around 1000 €.

When the scopes came out, there was not much competition – now, there is the Delta Optical, Vixen, etc. It is still difficult to get a scope with such good optics as here for 1000 € at other companies. You can, however, get one with a smaller illuminated dot. The 1-7 model is also most suitable for hunters (IPSC shooters could also use it), and it would be the perfect scope if the illumination would be a bit more powerful.

The models with target turrets are great for someone who wants to invest 600 €-900 € and wants to get the best possible optics with extended eye relief. The tactical model is competing with Primary Arms and Vortex at a lower price point – bellow 1000 €. As expected from Sightron, it has amazing tracking, which is rare for this price, and it also has better optics than most of the competitors.

For these scopes, the sale numbers are rising. That is because when people use them, they can see the good value for money – which is their main selling point. Even if they are made in the Philipines, they do care that their scopes are made with the same company philosophy in mind as the SIII. The warranty is 10 years.
