New for 2025, the Kahles K540i 5-40x56i sets a new standard for what extreme long-range precision optics can deliver. Kahles is one of the oldest and most respected optics manufacturers in the world — and the Kahles K540i represents the full expression of what that heritage and manufacturing capability produce when aimed directly at the most demanding end of the long-range precision shooting market.
40% Wider Field of View Than the K525i
The most immediately impressive specification of the Kahles K540i is the field-of-view improvement over its predecessor. Compared to the K525i, the K540i delivers a 40 percent wider field of view — measuring 30.6 feet at the low end and 3.9 feet at 100 yards at maximum magnification. At 40x, where the field of view is almost always the limiting factor in practical usability, that 40 percent improvement is not a marginal refinement. It is a meaningful operational advantage that keeps targets visible and transitions manageable at the extreme top end of the magnification range, where most competing scopes at 40x feel claustrophobically narrow.
5-40x Magnification for Extreme Distance
The Kahles scope K540i 5-40x magnification range covers everything from practical field use at the low end to the extreme long-range precision work that competitive ELR shooters and long-range hunters demand at the top. At 40x maximum magnification with a 56mm objective lens, the K540i gives shooters the optical reach to work effectively at distances that most riflescopes were never designed to handle — reading wind, identifying impacts, and making precise corrections at ranges where smaller scopes run out of usable magnification.
Comfortable Eyebox at Maximum Power
One of the most practical engineering achievements in the Kahles K540i DLR is the exceptionally comfortable eyebox maintained even at 40x magnification. High-magnification scopes typically punish shooters with a demanding eyebox that requires precise head position to find the full image — a problem that slows down shot-to-shot adjustments and increases shooter fatigue during extended sessions. The K540i's optimized eyebox at maximum power is the kind of real-world usability improvement that competitive shooters and hunters immediately appreciate when they get behind the glass under field conditions.
Extensive Illuminated Reticle Options
The Kahles optics K540i is available with a massive assortment of reticle designs — all illuminated — covering the preferences of different precision shooting disciplines and measurement systems. Whether you work in MOA, MRAD, or a specific competition reticle format, the K540i lineup offers a configuration that matches your system.
