Nikko Stirling rifle scopes of the Mountmaster series are characterized by a robust design that gives them incredible mechanical durability. In recent years, they have become very popular thanks to their excellent price‑performance ratio.
This model offers variable magnification 3–9x with adjustable parallax (AO) from 9.1 m to infinity. Inside the one‑inch waterproof tube (25.4 mm) there are lenses with multi‑layer anti‑reflection coating. To prevent moisture formation due to temperature changes, the tube is filled with nitrogen.
For precise aiming it uses a Half Mil Dot (HMD) reticle with 5‑level illumination in green or red. Reticle adjustment is done in clicks of 1/4 MOA (7 mm at 100 m) using two capped turrets.
The scope is supplied with a two‑piece mount for an 11 mm rail.
