Sightron riflescopes are manufactured in Japan. These scopes are renowned for their high quality and precise workmanship. The SIII series is the top line from this manufacturer; the riflescopes use a unique patented ExacTrack turret locking system. Seven-layer ZACT-7 coated lenses (patent ZACT-7) ensure maximum light transmission and perfect colour rendition without any distracting tint. The one-piece tube made of high‑quality hardened Aircraft aluminium with a matte black finish guarantees 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 some models from manufacturers in a higher class.
