Nikko Stirling Mountmaster 3‑9x40 ½ Mil Dot is a versatile riflescope designed for hunters and target shooters who want clarity, reliability, and value. Built on a 1‑inch matte black alloy tube, it’s waterproof, fogproof, and shockproof, making it a dependable optic for Australian conditions.
The adjustable objective (AO) lens allows parallax correction from 10 yards to infinity, ensuring sharp focus whether you’re plinking at close range or stretching shots further out. Multicoated lenses deliver bright, clear images, while the fast‑focus eyepiece helps you lock onto targets quickly.
Finger‑adjustable windage and elevation turrets provide precise ¼ MOA adjustments, and the illuminated half mil‑dot reticle offers reliable holdover points for varying distances. Supplied with sturdy 3/8" dovetail mounts, it’s ready to fit most rimfire rifles and air rifles straight out of the box.
Lightweight at just 380g and compact at 322mm long, the Mountmaster balances well on smaller rifles without compromising performance. Backed by Nikko Stirling’s lifetime warranty, it’s a proven optic for everyday use.
