Sightron riflescopes are manufactured in Japan. These riflescopes boast high quality and precision workmanship. The SIII series is the top series from this manufacturer; the scopes use a unique patented ExacTrack turret locking system. Seven-layer coated lenses (ZACT-7 patent) guarantee maximum light transmission and perfect colour rendition without any distracting tints. The one-piece tube made from high-quality hardened Aircraft-grade aluminium with a matte black finish ensures maximum durability and low weight. The riflescope is waterproof and shockproof, nitrogen-purged to prevent fogging. Sightron riflescopes are of very high quality and, in their price category, surpass the vast majority of the competition in both optical quality and mechanical workmanship, even outperforming many models from manufacturers in a higher class.
