Founded in 1898, KAHLES holds the title of the oldest scope manufacturer still active today. They’re known for their top-notch optics, serving various sectors like hunting, sports shooting, and law enforcement with high-quality optical devices. Their contributions include pioneering innovations like the adjustable ballistic drop compensation riflescope (1904) and the first waterproof riflescope with O-rings (1960). The Kahles K525I 5-25×56 embodies their dedication to quality and innovation, crafted specifically for tactical and competitive long-range shooting.

Before diving into my personal experience, let’s take a quick look at the specifications and background of the Kahles K525I.

The Kahles K525I 5-25×56 riflescope features a magnification range of 5-25x and a first focal plane for accurate aiming. It weighs 34.2 oz and measures 14.8 inches in length, making it manageable for shooters. With a field of view ranging from 21.3 ft to 4.5 ft at 100 yards, it offers versatility in target acquisition. The scope’s precise illuminated reticle and total elevation adjustment of 104.4 inches at 100 yards ensure accurate aiming over long distances.

Review of Kahles K525I 5-25×56

The first thing that struck me about the K525I is its outstanding build quality. Made entirely from metal with a rubberized ocular, it screamed durability and craftsmanship. The compact design, coupled with a relatively lightweight, makes it a versatile choice for various shooting scenarios.

The throw lever for magnification and parallax adjustment proved very handy. It allowed quick and precise changes, especially useful in dynamic shooting situations. With targets at varying distances and angles, I could rapidly adjust magnification and focus for a clear sight picture and accurate shots. This feature improved my shooting experience, providing the flexibility and efficiency needed in time-sensitive scenarios.

Optically, the K525I lives up to the expectations set by a high-quality scope. The 5-25x magnification range with a 56 mm objective lens delivers clear images, even in low-light conditions. The field of view is impressive, especially at 5 times magnification. With the 25x magnification on this scope, I was able to hit targets over 1000 yards without breaking a sweat.

One cool thing about the scope is that it works with a .50 BMG caliber. It won’t fog up inside, even in super cold weather, thanks to the nitrogen-purged design. Plus, it’s waterproof and comes with a 10-year warranty. It’s cool to see how confident Kahles is in their product’s durability and performance.

The illuminated reticle, positioned in the 1st focal plane, adds flexibility to targeting, and the stepless brightness adjustment is a practical touch. Having a zeroing key in the battery compartment made it easy for me to be prepared when I needed to make adjustments. The automatic turnoff feature after 2 hours is a small detail that contributed to conserving battery life.

The K525I’s turrets really impressed me. When I adjust them, the clicks are 1 cm at 100 meters, and I can elevate up to 29 mil, which is awesome for the highest precision long-range shooting. The turn indicator, zero stop, and those audible, tactile clicks made a big difference in my shooting experience. I could even choose where to put the windage and illumination turrets, giving it a customized feel just for me. I appreciate how they thought of everything to make it perfect for shooters like me.

Although the K525I is a great optic, there’s still room for improvement. It would be nice to have more reticle options since the ones available now are a bit limited. As for the cost, I did get maximum optical performance for what I paid. It was definitely a pricey choice, but I didn’t mind paying more because I got exactly what I wanted with this scope.

Kahles K525I 5-25×56 Pros and Cons 

  • Ambi Windage – You can purchase this scope with windage adjustment on either the left or right side of the scope.
  • Unique parallax adjustment – The parallax adjustment is built into the top turret, which is different than the standard side adjustment.
  • Glass Quality – This scope glass quality does not disappoint.
  • Reticle Options – Seven reticle options, although some are a bit unusual.
  • Price! – This is not a low cost scope.

Report Card


This scope never let us a down. At this price point, that is expected though.


At this price point you should expect top tier glass, and that is what you get.


Several reticle options to choose from.


The ability to select what side you want your windage adjustment on and the center mounter parallax adjustment makes this a very ergonomically friendly scope.


This scope is an investment, but if long range shooting is your objective, this is a good investment.
