The Kahles K18i 1-8x24i is an Austrian LPVO (Low Power Variable Optic) variable magnification riflescope developed by Kahles GmbH, the world’s oldest manufacturer of shooting optics. Designed specifically to meet the demands of high-end tactical competition and military special units, the K18i stands out as one of the premium benchmarks in the LPVO market thanks to exceptional optical sharpness, true 1× magnification and an 8:1 zoom range.
History and Development of the Kahles K18i 1-8x
Kahles, founded in Vienna in 1898 by Karl Robert Kahles, is now a subsidiary of the Swarovski Optik Group and benefits from the legendary optical know-how of the Austrian house. The K18i 1-8x24i was launched to meet the growing demand for a modern combat scope capable of covering both CQB (Close Quarters Battle) and engagement at 600 yards and beyond.
First presented at European trade shows, the K18i was quickly adopted by several elite European units as well as high-level competitors in the IPSC Mini Rifle, 3-Gun and PRS Gas Gun disciplines. Its design favors absolute turret precision, ultra-high daytime light illumination and best-in-class light transmission.

Operation and Technical Particularities
The K18i 1-8x24i uses an SFP (Second Focal Plane) optical architecture, a deliberate choice for fast-paced competition where the reticle remains the same size at all magnifications, ensuring instant and consistent aiming point reading. At 1×, the K18i offers true neutral magnification allowing for red-dot-like use with two eyes open, ideal for ultra-fast engagements at close range.
Its illuminated reticle is one of its signatures: the light cell achieves one of the most powerful daytime intensity in full sunlight on the market, comparable to that of a real red dot, without a stray halo. The clickable turrets accurate to 0.1 MRAD, the Swarovski quality of the coated glass and the proven mechanical robustness in combat zones make the K18i a precision tool adopted by the most demanding operators. The quick zoom lever (throw lever) allows you to instantly switch from 1× to 8× with a thumb movement.
Variants and Versions
In addition to the K18i 1-8x24i presented here, the Kahles tactical range offers several other models adapted to different needs: the Kahles K16i 1-6x24i, a more compact and lightweight version oriented CQB; the Kahles K328i 3.5-28×50, a long-range scope for PRS and tactical shooting at very long ranges; and the Kahles K525i 5-25×56, the absolute reference in precision shooting. Several reticles are available for the K18i, including the 3GR (3-Gun), which is particularly popular with international competitors.
Users and Armed Forces
The Kahles K18i equips several European special units, including in gendarmerie and intervention forces in Germany, Austria and Central Europe. On the civilian side, it has won the international IPSC Mini Rifle and 3-Gun competitions where several world champions have adopted it as their preferred lens. It is also popular with European hunters looking for a versatile scope for stalking, driven hunting or mixed shooting.
Civil Possession in Switzerland
In Switzerland, the Kahles K18i 1-8x24i is freely available for purchase from specialist gunsmiths and distributors of precision optics.

The conditions include: being at least 18 years old, not being under general curatorship, and not presenting a reason for refusal. The cultural proximity to Austria makes the Kahles brand a particularly popular choice for Swiss sport shooters who demand a high level of quality.
