The Aim Sports RT503F delivers fast target acquisition with its 33mm objective lens and dual-color reticle system. This full-size reflex sight combines affordability with tactical performance for competitive shooters and hunters who demand reliable optics without premium pricing.
What Makes This Different
The RT503F stands apart with its switchable red and green illumination system, allowing shooters to adapt to varying light conditions and backgrounds. Unlike basic red-dot sights, this optic features multiple reticle patterns including dot, crosshair, and circle-dot configurations. The 33mm objective provides a wide field of view compared to compact 20mm alternatives, enabling faster target transitions and improved situational awareness.
