Sightron SIII Competition 45X45 1/10MOA ED FCH

The Sightron SIII Competition 45x45 ED is purpose-built for competitive benchrest, F-Class and precision shooters demanding exceptional optical clarity and precise mechanical performance. Featuring a fixed 45x magnification and premium ED (Extra-low Dispersion) glass, this riflescope delivers outstanding target definition, reduced chromatic aberration and superior color fidelity.

The SIII Competition series has earned a strong reputation among benchrest and long-range shooters thanks to its reliable tracking and repeatable turret adjustments. Sightron’s proprietary ExacTrack windage and elevation system maintains constant pressure on the erector assembly to ensure consistent point of impact even at extreme adjustment ranges.

Its 30 mm one-piece aircraft-grade aluminum tube provides excellent rigidity and long-term durability while keeping overall weight low. The target-style resettable turrets feature ultra-fine 1/10 MOA click adjustments, making the scope ideal for precision competition shooting and benchrest applications.

The side-focus parallax adjustment allows precise focusing from 10 yards to infinity, making the optic suitable for both rimfire and centerfire disciplines. ED glass elements combined with Sightron’s Zact-7 Revcoat multi-coating technology improve light transmission, contrast and overall image sharpness.

The etched glass reticle is optimized for ultra-precise aiming on competition targets. Waterproof to IPX7 standards, nitrogen-filled for fogproof performance and shock resistant, the SIII Competition 45x45 ED is engineered for consistent high-level performance in demanding shooting environments.
