Leica Fortis 6 2.5-15x56i Riflescope Review | Optics Trade Reviews

  • Maja 

The Leica Fortis 6 2.5-15x56 riflescope was released at IWA 2019, but since then the series has failed to make a significant impact in the market. I believe that these scopes are a hidden gem and it's a real shame that they haven't had more success.

Leica Fortis 6 enters the market

For a while, I was in the dark about the Fortis 6 series when researching European riflescopes with six times zoom power. We tend to think about Swarovski's Z6i—which has been on the market for over 15 years now—or Zeiss' V6. Even before that time though, Doctor V6 was quite popular among hunters looking for a six-times zoom scope.

I didn't start paying attention to the Fortis 6 series until I saw this riflescope, and it completely changed my perception. Leica had 10 years to make a product that could compete with Swarovski's Z6i, which has been dominating the European market for years.

Magnus was the first direct competitor to Swarovski's Z6i series, and in many ways, it surpassed the Z6i. However, with the introduction of Swarovski's Z8i, the Magnus became much more expensive than the Z6i. So, Leica decided to create a riflescope similar to the Z6i but at a more affordable price, and thus came the Fortis 6.

The Fortis 6 series offers the following models of riflescopes:

Physical properties of Fortis 6 2.5-15x56i 

Compared to other riflescopes on the market, Fortis 6 models are relatively modern. They boast high-quality turrets similar to those found on Magnus models, but at a lower price point – around 10%, 15%, or 20% less than Swarovski Z6i models, depending on the specific model.

Leica Fortis 6 2.5-15x56i is significantly heavier than the Swarovski Z6i at 780 grams. In addition, the riflescope is quite long at 36 centimeters. The objective outer diameter is 62 millimeters which is standard for all night vision optics and clip-ons.

Mounting on a rifle

The Fortis 6 2.5-15x56i riflescope has a 30 mm central tube diameter and can be mounted on a rifle with 30mm scope mounts rings. The model with a Zeiss ZM/VM rail standard is also available for purchase.

The reticle on the Fortis 6 2.5-15x56i is in the second focal plane and very thin at higher magnifications, which is great. The only downside is that the riflescope is only available with the L4A reticle.

By producing riflescopes with only one reticle, Leica was able to lower the overall costs for manufacturing Fortis 6 models. The selected reticle is illuminated.

Illumination control

The side turret is used to control the illumination system, which has nine intensity levels that span from daytime bright down to low light. The illuminated dot in the center is quite small and thin- making it appear delicate.

The drawback I have to mention about the Fortis 6 2.5-15x56i scope is that there are only a small number of illumination intensity levels available.

The Fortis 6 2.5-15x56i is available with normal hunting, capped, low-profile turrets. You can also select a model with BDC turrets - the same as on Magnus models.

The hunting turrets are of multiturn type and have 100 clicks in one revolution. The click value is one centimeter per 100 meters. Unlike many of its competitors, this riflescope features turrets with a nice metallic feel. Additionally, the elevation range is 20MRAD- more than enough for most users.

The riflescope with a BDC turret feature a high-quality locking mechanism that only requires one turn and has 95 clicks on total. The BDC turret also has a zero stop and single turn function. These functions aren't available on models with capped turrets.

The turrets are resettable and have a good feel. Especially the BDC turrets. You can buy 12 different ballistic rings, which have different engraved values for different calibers.

The Leica BDC Direct dial set is one of the best on the market. It's only rivaled by the Swarovski BTF, but in terms of build quality, this one is even nicer because it's fully metallic. Zeiss has a plastic BDC turret and so does Swarovski—but Leica's BDC direct dial set is made entirely of metal.

The Fortis 6 2.5-15x56i model is the only one in the whole Fortis 6 series that has an adjustable parallax, which is a great feature. It can be adjusted from 50 meters to infinity. It produces a nice click on 100 meters and has a nice firm feel with plenty of travel.

Optical performance

The optical performance is 2.5x at the lower end and 15x at the upper end with a 56-millimeter objective lens—which is already a known formula for low-light riflescopes with six-times zoom.

The field of view is 17 meters at 100 meters, which means it has a wider field of view than the Z6i. Furthermore, the light transmission is 92%, once again better than the Z6i at least on paper.

The eye relief is 90 millimeters. The eye box when you look through it is just as good if not better than the Swarovski Z6i's. Leica managed to make a riflescope that has superior optics compared to other scopes in the six-time zoom class for a really affordable price.

In terms of price, Leica did a fantastic job--Fortis 6 is easily 15-20% cheaper than its competitors. When considering optical performance, Fortis 6 ranks just above similar brands like Docter (now Noblex), Zeiss V6, and Leopold VX6.

Where are Leica Fortis 6 riflescopes made?

The Fortis 6 rifle scope is a reliable, top-of-the-line product. It's made in Leica's factory located in Portugal. In addition to the original factory establish back in 1973, recent investments amounting to over 20 million euros have gone into expanding and modernizing the facilities.

Leica claims that the products produced in Portugal reach the same level of quality as those from Germany. I agree with this claim; if you examine Geodvid and Fortis 6, it's clear that there isn't a notable difference in terms of quality between products coming out of both countries, at least to me. Additionally, by changing where they produce the products, Leica has been able to lower prices when pitted against its competitors- which is great news for users.

Positives first: what do we like about this riflescope?

The optical quality for this price point is incredible, and you'll be hard-pressed to find a better value. For 2250 euros, the optics are terrific. It's a great investment. I love the look and feel of this product, as well as the amazing BDC turrets. I think it's great that even though Fortis 6 is technically a tier below Magnus, it still gets the same top-quality BDC turrets.

The scope's field of view is excellent at 17 meters at 100 meters. Additionally, the size of the illuminated red dot in the reticle is perfect. Another great feature about this scope is that it is available with Zeiss ZM/VM mounting rail option.

Pros summary:

  1. price
  2. high-quality BDC turrets
  3. wide FOV
  4. perfect dot size
  5. Zeiss ZM/VM mounting rail option

What could have been better?

In my opinion, the nine-step illumination range on the riflescope isn't good enough. The position sensor that turns off the scope's illumination when placed sideways or up and down is a great feature, but I think they could make more intensity levels.

I believe that there is room for improvement in terms of quality. If we don't consider the number of intensity levels, Fortis 6 is quite similar to Magnus. Therefore, I think there will be competition between Magnus and Fortis 6, even though Magnus does have additional features which make it better than Fortis 6. The only problem is that its price is almost 1000 euros higher.

So I think that Leica should consider making a Magnus with an eight-time zoom, rather than a six-time.

I also think the scope could be a bit smaller; 36 centimeters is pretty large.

Cons summary:

  1. only 9-levels of illumination
  2. could have more features
  3. large riflescope

Final thoughts

Among European rifle scopes, the Fortis 6 2.5-15x56i is an excellent option if you are looking for a scope with a six-times zoom that can be used in low light and for long-range hunting. You will be hard-pressed to find the scope of this quality at such an affordable price.

If you want an excellent six-times riflescope for a reasonable price, this is one of the best options.
