Features
- Premium Optical System – Fully multi‑coated high‑definition glass and a 50 mm objective deliver exceptional light transmission and edge‑to‑edge clarity, even in low‑light conditions.

- Side Parallax / Focus – Side‑mounted dial adjusts parallax from 50 m to infinity for a crisp reticle image and elimination of focal shift.
