Kahles K318i 3.5-18×50 Riflescope – MRAD | Ultra-Compact Precision Optics

The Kahles K318i 3.5-18×50 MRAD Riflescope is a high-performance optic built for shooters who demand superior clarity, mechanical reliability, and compact design. Designed with input from professional marksmen, the K318i stands out in the premium riflescope market thanks to its ultrashort construction, first focal plane reticle, and patented TWIST GUARD windage system.

Precision Engineering in a Compact Design

At only 12.3 inches in length and weighing just 950 grams, the Kahles K318i is engineered for space-critical setups where rail real estate and weight matter. Despite its compact size, it offers an outstanding field of view (9.3 to 2 m/100m) and superior twilight performance (13.2–30)—perfect for long-range shooting at any time of day.

First Focal Plane Advantage

This riflescope features illuminated reticles in the first focal plane, meaning the reticle scales proportionally as magnification changes. This allows accurate holdovers and range estimations at any zoom level, making the K318i ideal for both tactical and competition use. The reticle remains razor-sharp and functional whether you’re zoomed out at 3.5x or fully dialled in at 18x.

Choose Your Ideal Reticle

The K318i MRAD is available with three top-tier reticle options:

• TREMOR 3 – Designed for advanced shooters with rapid target acquisition and wind-hold reference.

• MSR/Ki – An extremely versatile reticle optimized for speed and precision.

• SKMR4 – A clean and functional grid-style reticle for maximum accuracy in field conditions.

Each reticle is finely etched and illuminated, ensuring performance in low-light conditions without overpowering your sight picture.

Unmatched Ergonomics and User Comfort

What sets the K318i apart is its ergonomically refined layout. The patented parallax adjustment is conveniently integrated into the elevation turret, allowing rapid corrections without shifting your shooting position. The windage turret is available on either the left or right side, catering equally to left- and right-handed shooters. This smart arrangement means all critical controls are accessible and visible while maintaining your cheek weld and shooting position.

TWIST GUARD Windage – Patented Protection

Kahles introduces its TWIST GUARD windage system, a freely rotating end cover that prevents accidental turret movement without requiring traditional locking mechanisms. It’s a clever solution that delivers secure adjustments without delay, keeping you focused on your shot, not your equipment.

Exceptional Build Quality

Built around a rugged 34mm main tube, the K318i is shockproof, waterproof, and fogproof, ready to withstand the harshest environments. With dioptric adjustment from +2 to -3.5, a wide parallax range (25m to infinity), and a smooth 0.1 MRAD click value, this scope offers repeatable accuracy and refined tactile feedback that shooters can trust.
