  • Technical Specs
  • Thanks to its compact dimensions and a large, 50 mm objective lens, it is an extremely versatile riflescope for hunting from blinds and when stalking. Its outstanding zoom factor and a minimum magnification of 1.8x also make it the ideal choice for driven hunts. This riflescope is perfect for users for whom a 56 mm is too large but the light gathering ability of a 42 mm seems too low. It unites advantages such as a compact construction, versatile use, very easy mounting and first-class optics. For instance, the combination of minimal vignetting and the large, effective diameter of its objective lens, provides exceptional light-gathering ability and the highest, outstanding transmission value of around 92% ensure optimum identification up to the last minutes of shooting light. The large field of view provides a better overview and hence a faster sight.
