Features

Large Field of View with Multi-Coated Lens: Engineered with advanced anti-reflective lens coatings, this sight maximizes light transmission for unmatched clarity, allowing you to quickly lock onto targets with pinpoint precision. The 0.95'' × 0.75'' window delivers a greater sight picture, ensuring faster target acquisition and quicker follow-up shots.
Side-Loading Battery: Effortless battery replacement without removing the optic ensures hassle-free re-zeroing. A high-end CR1632 battery offers easy accessibility while maintaining steady performance. 
3 MOA Dot + 32 MOA Circle: Switching between dot-and-circle, dot-only, or circle-only reticles, you can tailor your aiming solution to any shooting scenario. The sharp and bright dot-and-circle reticle provides a cutting-edge aiming experience.

    I was on the fence about ordering this optic but it does not disappoint. I have this and a trijicon rmr and I would definitely prefer Osight after using it. Fit like a glove on my Glock 19
