Great red dot with clear image - Holosun Paralow HS503C Circle Dot Sight

The optic has a lot of light transmission thru the tube and the reticle is prettty clear .line up perfectly with my buis ! Love this optic . It comes with a bikini cover but just make sure you put the battery in the right way. Which is actually upside down since the battery location is on the bottom or it won’t be able to close right ..
