The Sightron S1 G2 4-12x40 (MPN 32009) is a variable-power hunting riflescope built on a 1-inch (25.4 mm) one-piece aircraft-grade aluminium main tube. Designed for field hunting and range work, it pairs a 4-12x magnification range with a 40 mm objective lens and a non-illuminated wire Mil-Dot reticle positioned on the second focal plane. The optical system utilises Sightron MC-333 fully multi-coated glass to minimise glare, housed in an IPX7 waterproof and nitrogen-purged chassis rated for up to 1,000 G of recoil shock. Note that while catalogue listings may mention an adjustable objective, factory specifications for model 32009 confirm a fixed 100-yard parallax setting with low-profile, capped 1/4 MOA adjustment turrets.
Key Features
- MC-333 Multi-Coated Optics: Fully multi-coated glass elements suppress glare and chromatic aberration across the entire 4x to 12x zoom range.
- Second Focal Plane Mil-Dot Reticle: Wire reticle provides standard holdover and range estimation markings without altering subtension sizes as magnification increases.
- Capped Hunting Turrets: Low-profile adjustments feature 1/4 MOA click values, offering 15 MOA per rotation and 60 MOA total travel for both windage and elevation.
- Rugged Chassis Sealing: One-piece aluminium 1-inch tube is nitrogen-gas charged, shockproof to 1,000 G, and waterproof to IPX7 standards (submersible to 1 metre for 30 minutes).
- Lightweight Field Profile: Total mass of 13.6 ounces (385.5 g) reduces carry fatigue on walking sporter rifles.

Who is the Sightron S1 G2 4-12x40 Riflescope for?
- Feral pest and medium game hunters targeting deer, fox, and rabbits — Benefits from a 13.6-ounce (385.5 g) total weight and a 4-12x magnification range that pairs with a fixed 100-yard parallax setting to minimise rifle heft during long treks across rugged bush terrain.
- Centre-fire rifle target shooters operating at standard distances — Utilises this hunting riflescope's 40 mm objective lens and 1-inch tube to deliver 60 MOA of internal windage and elevation travel, calibrated precisely for targets placed at 100 yards and beyond.
Less suitable for: Close-range shooting under 50 metres, where the fixed 100-yard parallax introduces reticle error (an adjustable objective scope focusing down to 10 yards is better suited), as well as long-range precision matches requiring exposed, multi-revolution tactical dials with mechanical zero stops.
