The HS510C is Holosun's flagship open reflex sight — massive viewing window, dual reticle (65 MOA circle for fast CQB acquisition + 2 MOA dot for precision), solar backup, and 50,000-hour battery life. It's the optic that made Holosun a serious competitor to Aimpoint and EOTech at less than half the price.
Designed for AR-15, AR-10, and shotgun platforms. The open reflex design gives a much larger field of view than tube-style red dots, making target acquisition faster with both eyes open. IP67-rated for water and dust resistance — survives rain, sweat, and accidental dunks.
