Hawke Sidewinder Tactical riflescopes are the latest models of the Hawke series and they raise the standards in all respects. The design team decided that the lens diameter is going to be 42 mm which is an optimal value for keeping the riflescopes light and therefore ideal for low mounting on rifles, when compared to the previous Hawke Sidewinder 30IR series. They have quality glass and multi coated lens surfaces to ensure superb resolution and contrast, which is especially important for long-range shooting. The reticle of the Hawke Sidewinder Tactical is placed in the second focal plane and has line-dots divided in such a way, that the distance of 1 mrad equals one dot at 20x magnification or, with some models, at only 10x magnification. All reticles are illuminated with red or green light and the construction of the riflescope can withstand the recoil of even the most powerful calibres. Hawke Sidewinder Tactical riflescopes are waterproof and nitrogen filled. The warranty period is 10 years.
