Spirit levels for riflescope, 25mm, Vortex

The spirit level (libela) on riflescopes with tube diameter of 25 mm from the VORTEX. Spirit level (libela) helps to always hold the weapon in the same (horizontal) position during firing. By this is achieved greater firing accuracy due to elimination of movement of aim point. For airsoft guns it is also necessary to always shoot so that hop-up protuberance is on top. Any slope will cause undesirable lateral rotation of the projectile and thus substantial inaccuracy when shooting at longer distances. Simple installation and reliable operation. An important accessory for airsoft, sports, as well as tactical shooting.
