Are you looking for a compact red dot sight with an RMR mount (footprint) that delivers fast target acquisition and precise aiming? Do you need a red dot sight with easy battery replacement directly in the field? Want a green illuminated reticle for CQB and precision shooting? Then OSIGHT C GREEN is the right choice. It combines simplicity with top-tier build quality, highlighted by a large 24 × 19 mm window offering a wide field of view for rapid target acquisition. The bright, crisp reticle (green 3 MOA dot, 32 MOA circle, or both) delivers speed and precision depending on the situation. Side-mounted CR1632 battery replacement allows quick changes without re-zeroing. The 7075-T6 aircraft-grade aluminum body with Type III hard anodizing provides excellent impact and wear resistance. IPX6 protection and a motion-activated sensor (3 min auto-off) save battery life and ensure the sight is always ready. The lenses feature fully multi-coated (FMC) optics for higher light transmission and better contrast in low light. Thanks to the standard RMR footprint, OSIGHT C can be mounted directly onto compatible pistol slides.
