Kahles K312, K418 and K624 riflescopes have been designed for long range shooting and all their qualities have been tweaked to ensure the best possible results. All previously mentioned riflescopes are designed especially to be used on the most powerful rifles in the harshest conditions. They are nitrogen filled to prevent dew build up at low temperatures, waterproof and equipped with parallaxes error correction adjustment. Reticle adjustment domes can be covered or opened to ensure easy correction when using gloves. The Kahles K312 has the reticle placed in the first focal point to ensure easy use in low light conditions. This means that the distances between different points in the reticle do not change in spacing by different magnifications. Such properties are especially important for distance calculations and long range aiming changes without changing the reticle’s position. Kahles K418 and K624 have the reticle placed in the second focal point and are therefore designed to ensure small target overshadowing at high or maximum magnification. All of the above series of riflescopes have multi coated lens surfaces for the best image sharpness and light transmission rates. The limitless warranty for Kahles K312, K418 and K624 extends to 30 years.
