The newest long distance shooting scope has arrived, the Kahles K540i series, available in both regular and Dynamic Long Range (DLR) configurations. I’m already a fan of the previous K525i DLR from Kahles so it’s great to see continued development of the line up. Kahles clearly has extreme long distance in mind with the design of the K540i, with the very capable 5-40x magnification range.
Companies using the phrase ‘game changer’ can be a little cliche sometimes but Kahles do have something big to boast about with this scope. The biggest upfront feature is the 40% increase in field of view from the previous K525i. My favourite part from the previous model is the ability to order the scope with the windage turret on the left or right side with the twist guard. The other innovative feature continued over is the parallax wheel under the elevation turret.


The elevation turret on the non DLR version offers 160 clicks per rotation, I’m guessing that’s to keep the entire elevation range within the two rotations. The DLR model has 10 MIL per rotation and features large turret numbers making them a little easier to read.

The K540i has three reticles available including the AMR, MSR2/Ki and SKMR4+. The reticles are illuminated and in the first focal plane. Everyone has their own preferences but I’m very happy to see the MSR2 included as its one of my favourites.



There’s a 56mm objective lens and something to note when looking at scope rings is the 36mm matintube diameter. Overall the K540i is bringing a lot to the table with an impressive field of view coupled with the mammoth magnification range. I like the reticles they have available and the customisation of windage turret location when ordering. If your on the hunt for a ELR scope and it’s in your budget, it might be worth getting hands on with one.
