When Kahles unveiled the K864 8-64x56 mm riflescope at SHOT Show 2026 in Las Vegas, it wasn’t positioned as a refinement of an existing platform or a do-everything optic stretched to its limits. This is a riflescope conceived specifically for F-Class competition, where precision lives at the intersection of optical clarity and the shooter’s ability to read subtle environmental changes at distance.
The K864 has an 8-64x magnification range paired with a 56 mm objective, a combination aimed squarely at long-range targets where the margin between a winning score and an average one can be measured in fractions of a millimeter. High magnification alone is nothing new, but Kahles’ focus here is maintaining image quality and usability all the way to the top end. Even cranked up to 64x, the sight picture remains bright and controlled, avoiding the tunnel-like effect that often plagues extreme magnification optics.
Central to that experience is what Kahles calls its VISIONFLEX optical design. Compared with the company’s earlier K1050 at 40x, the K864 offers a dramatically wider field of view, while also delivering a more forgiving eyebox. In practical terms, this means more visible wind indicators, easier mirage interpretation and less fatigue during long strings of fire, all without backing off magnification. It’s an optical approach that prioritizes awareness as much as raw resolution.
Mechanically, the K864 leans into the demands of precision competition. Adjustments are handled in 1/8-MOA clicks, allowing extremely fine point-of-impact corrections at distances where even minimal errors are magnified. The scope uses a second focal plane design with a non-illuminated MOAK+ reticle, reflecting its singular focus on daylight, known-distance competition rather than low-light versatility. A 36 mm main tube provides generous adjustment range, while features such as a zero stop, revolution indicator and top-mounted parallax control emphasize repeatability and speed under pressure.
Ergonomics were clearly part of the brief. The elevation turret uses high-contrast labeling that spans 20 MOA per revolution, making it easier to confirm settings at a glance. Windage is positioned on the right side, parallax adjustment is top mounted ranges from eight yards to infinity, and the overall layout favors shooters who dial constantly and demand absolute trust in every click.
In the current landscape, the K864 sits alongside other no-nonsense competition optics (like those from Nightforce), but it distinguishes itself by committing fully to a single discipline rather than chasing broader appeal. With an MSRP of $5,049 and availability slated for March 2026, it’s clearly aimed at shooters who see equipment as a precision instrument rather than a multipurpose accessory.
By stripping away crossover features and doubling down on optical performance and field of view, the Kahles K864 riflescope feels less like an incremental update and more like a statement of intent. For F-Class competitors who want an optic designed solely around their discipline, it represents a focused step forward.
