Sightron

Hunting and tactical riflescopes (SI, SII, SIII, SV series) favored in benchrest and rimfire circles; airgun-specific positioning not established.

Sightron is owned by the Japanese optics group Kenko Tokina, which also runs Sightron's Philippine manufacturing facility for its mid-range lines. Its warranty is tied to proper distributor import records by country, which matters more for buyers of used or gray-market Sightron glass than for most airgun-native brands.

Warranty: Warranty service requires proof the scope was imported through an authorized regional distributor; community reports describe this as stricter than a simple lifetime warranty, particularly for scopes bought used or imported informally.
