Kahles K540i Refined is a first focal plane long-range riflescope built around a true 8x zoom and a wide field of view for fast target transitions. This configuration uses the SKMR4+ reticle with left-side windage for ergonomic control.
The Kahles K540i Refined is designed for demanding precision shooting where clarity, turret readability, and repeatable adjustments matter. With its 5-40x range and 56 mm objective, Kahles K540i Refined 5-40x56 36 mm Riflescope supports both detailed spotting at distance and refined aiming through the SKMR4+ first focal plane reticle. The elevation and windage system uses 0.1 MRAD clicks with CCW adjustment direction, and the parallax is top-mounted for fast access without breaking position. This left-side windage setup keeps controls accessible while staying behind the rifle.
