STYRKA'S S3 Red Dot Sight is a rock-solid weapon's optic that is designed to provide laser-sharp aiming while also enduring the rigors of the battlefield. At the core of the sight is a brilliant 5 MOA Green Dot illuminated reticle, which is set to be parallax-free at 50 yards but features reduced parallax and point-of-aim errors beyond this mark due to the Double-Lens Optical System and the Dot Color Indexed Coatings. The LED illumination system is powered by one CR-2032 battery and offers six brightness levels, Auto Shut Off, and Auto Return to the last brightness level. Additionally, the optical system incorporates a 1x magnification, a 21mm objective aperture, an unlimited eye relief, a wide field of view, and fully multi-coated anti-reflection lenses.

The housing is made of lightweight and durable 6061-T6 aluminum alloy that is well-suited for any task or conditions. The device also includes a honeycomb anti-glint filter that kills the glare off the objective lens and helps an observer to remain unobserved. Among other highlights are a fogproof and waterproof (submersible) performance that is integrated with elevation and windage turrets, adjustment tools, and a built-in Picatinny/Weaver mount.
