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 red-illuminated reticle for CQB as well as precision shooting? Then OSIGHT C is the right choice. It combines simplicity with top-tier build quality, highlighted by a large 24 × 19 mm window that offers a wide field of view for fast target acquisition, while the bright and crisp reticle (red 3 MOA dot, 32 MOA circle, or both) delivers speed and precision depending on the situation. The side-loading CR1632 battery allows quick replacement without re-zeroing. The 7075-T6 aircraft-grade aluminum construction with Type III hard anodizing provides excellent impact and wear resistance. IPX6 protection and a motion-activated sensor (3 min auto-off) help save battery life and ensure the optic is always ready. The lenses feature fully multi-coated (FMC) optics for higher light transmission and improved contrast in low light. Thanks to the standard RMR footprint, OSIGHT C can be mounted directly on compatible pistol slides.
