Kronos 3-12x56 SF SIR FBR

Kronos 3-12x56. You can select it in various designs of glass etched reticles. Suitable for passionate hunters mainly. Riflescopes are designed and tested in the Czech Republic. The main feature is the construction of one-piece main tube with a diameter of 30mm. This value will guarantee a sufficiently sharp image even in low light conditions. Since this model is intended for hunters mainly, turrets are hidden and low profiled. Hunters can safely wear their rifles on strip and turrets will not move. If you need to zero your scope you will certainly appreciate the possibility of screw zeroing done by a coin. For a maximum usable value the screw is made of steel.We have also added a diopter correction from -2 to +2. Since the riflescope is suitable for high caliber rifles, we have equipped it with an adjustable side parallax with range from 15yds to infinity. Big wheel is included with scope and it allows more comfortable manipulation. On the same turret, you can control illumination which is always appreciated in low light conditions or if your target does not have enough contrast with reticle. Illumination is in red color with 11 levels of intensity. All lenses were made of glass and coated with a special anti-reflective coating. Plastic caps that are protecting the outer lenses are included wich scope. If the sunlight is really sharp and the coating is not sufficient for you, sunshade is included and will solve all these problems. Or you can purchase a Kill Flash to reduce sun glare.
