The Sightron Si G2 Series 4-12x40 Riflescope With Adjustable Objective (Duplex Reticle) provides magnified target acquisition and versatile parallax correction across rimfire, centrefire, and air rifle platforms. Built around a 1-inch (25.4 mm) single-piece aircraft-grade aluminium main tube, this second focal plane optic features Sightron proprietary MC-333 fully multi-coated glass and a 40 mm objective bell. Its integrated adjustable objective focuses down to 10 yards, eliminating parallax error for close-range pest control while offering up to 12x magnification for extended hunting distances. Rated to withstand 1,000 Gs of shock force, the nitrogen-purged assembly delivers fogproof and waterproof performance in adverse field environments.
Key Features
- Adjustable Objective Focus: Front bell rotates from 10 yards to infinity to eliminate parallax error across short and extended shooting distances.
- Fully Multi-Coated Optics: Employs proprietary MC-333 lens coatings across a 40 mm objective lens for enhanced light transmission and target clarity.
- Capped Hunting Turrets: Provides 1/4 MOA click values with 15 MOA per revolution and 60 MOA total windage and elevation adjustment.
- Rugged Weatherproof Build: Machined 1-inch aluminium tube is nitrogen-purged and O-ring sealed to provide waterproof, shockproof, and fogproof reliability.
- Standard Ring Compatibility: Mounts directly into standard 1-inch scope rings on Picatinny, Weaver, or rimfire dovetail rails.

Who is the Sightron Si G2 Series 4-12x40 Riflescope With Adjustable Objective, Duplex Reticle, Second Focal Plane, 1" Tube for?
- Small-game hunters and pest controllers — requires an adjustable objective hunting riflescope with parallax focus reaching down to 10 yards and a versatile 4-12x magnification range to reliably engage targets from short-range rabbit control out to medium-range fox shooting.
- Rimfire precision shooters and general target practitioners — benefits from this 17.1 oz adjustable objective hunting riflescope with a 40 mm objective lens and 1-inch main tube, maintaining light field portability while providing fine parallax correction at typical 25-yard and 50-yard rimfire distances.
Less suitable for: Target shooting at extreme close quarters under 10 yards where parallax distortion can occur, long-range ELR or PRS disciplines requiring elevation adjustments exceeding 60 MOA total travel (where a 30 mm or 34 mm tactical scope with exposed turrets is better suited), and heavy magnum rifles such as .338 Lapua or .50 BMG that demand heavy-duty tactical optics.
