Zephyr 4-16x50 SF SIR 1/2 Mil-Dot

Push your limits with Zephyr riflescope

Zephyr series is our flagship. And that inherently represents model 4-16x50. You can select it in various designs of glass etched reticles. Suitable for sports shooter or passionate hunter. 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. Operation with open turrets and possibility of self-locking is quick and easy. 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 10yds 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 and green color with 5 levels of intensity. All lenses were made of glass and coated with a special anti-reflective coating. Plastic caps which are protecting the outer lenses are included wich scope. If the sunlight is really sharp and coating is not sufficient for you, sunshade is included and will solve all these problems.
